# How to Create a Search Module Provider

In this document, you’ll learn how to create a Search Module Provider and the methods you must implement in its main service.

---

## Implementation Example

As you implement your Search Module Provider, it can be useful to refer to an existing provider and how it's implemeted.

If you need to refer to an existing implementation as an example, check the [Postgres Search Module Provider in the Medusa repository](https://github.com/medusajs/medusa/tree/develop/packages/modules/providers/search-postgres).

---

## Create Module Provider Directory

Start by creating a new directory for your module provider.

If you're creating the module provider in a Medusa application, create it under the `src/modules` directory. For example, `src/modules/my-search`.

If you're creating the module provider in a plugin, create it under the `src/providers` directory. For example, `src/providers/my-search`.

> **Note**
>
> The rest of this guide always uses the `src/modules/my-search` directory as an example.

---

## 2. Create the Search Module Provider's Service

Create the file `src/modules/my-search/service.ts` that holds the implementation of the module provider's main service. It must extend the `AbstractSearchProviderService` class imported from `@medusajs/framework/utils`:

```ts title="src/modules/my-search/service.ts"
import { AbstractSearchProviderService } from "@medusajs/framework/utils"

class MySearchProviderService extends AbstractSearchProviderService {
  // TODO implement methods
}

export default MySearchProviderService
```

An abstract class for search providers. Extend this class to create a search
provider.

A search provider translates the Search Module's provider-agnostic input into
the calls of a search engine, such as Meilisearch or Typesense: it creates and
migrates the physical indexes, writes and deletes documents, and runs queries.
The Search Module owns everything around it, including index definitions,
batching, task tracking, and reindexing.

### constructor

The constructor allows you to access resources from the module's container using the first parameter,
and the provider's options using the second parameter.

If you're creating a client with a search engine, do it in the constructor.
Establishing a connection with the search engine should happen in `onApplicationStart`.

#### Example

```ts
import { Logger } from "@medusajs/framework/types"
import { AbstractSearchProviderService } from "@medusajs/framework/utils"

type InjectedDependencies = {
  logger: Logger
}

type Options = {
  host: string
  apiKey: string
}

class MySearchProviderService extends AbstractSearchProviderService {
  static identifier = "my-search"

  protected logger_: Logger
  protected options_: Options
  // assuming you're initializing a client
  protected client

  constructor (
    { logger }: InjectedDependencies,
    options: Options
  ) {
    super()

    this.logger_ = logger
    this.options_ = options

    // assuming you're initializing a client
    this.client = new Client(options)
  }
}

export default MySearchProviderService
```

### Handling unsupported features

There's no list of features to declare. If a query asks for something your engine can't
express, throw; if an index definition asks for something it can't hold, throw from
`upsertIndex` so the error surfaces at startup. Returning a slightly different result is
the one outcome to avoid, since callers can't tell it apart from a correct one.

### identifier

Each search provider has a unique identifier used to register it and to bind
an index definition to it. An index definition selects a provider by setting
its `provider` property to this identifier. You can also use this identifier
in `medusa-config.ts` to configure the default provider for the Search Module.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  static identifier = "my-search"
  // ...
}
```

### clearIndex

This method removes every document from an index without deleting the index itself.
The Search Module uses it to empty an index before reseeding it in place.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async clearIndex({
    index,
  }: {
    index: string
  }): Promise<SearchTypes.SearchTask> {
    await this.client.deleteAllDocuments(index)
    return { index, status: "succeeded" }
  }
}
```

#### Parameters

**clearIndex**

- `_input`: `object` — The index to empty.
  - `index`: `string` — The index's physical name.

#### Returns

**clearIndex**

- `Promise`: Promise<[SearchTask](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchTask)> — The write's task.
  - `id`: `string` (optional) — The ID identifying the write in the search engine, which is passed back to the provider's `waitForTask` method. It's set only for a deferred write, since a provider applying writes inline has nothing to identify.
  - `index`: `string` (optional) — The name of the index the write was applied to.
  - `status`: [SearchTaskStatus](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchTaskStatus) — The write's status.
  - `error`: `object` (optional) — The error that made the write fail, if its `status` is `failed`.
    - `message`: `string` — The error's message.
    - `code`: `string` (optional) — The error's code, as reported by the search engine.

### deleteDocuments

This method removes every document matching the given filters.

Deleting by ID isn't a special case — it arrives as a filter on the primary key, such
as `{ id: ["prod_1", "prod_2"] }`. Recognize that shape and use your engine's
delete-by-ID path, which is usually much faster. If your engine can't delete by
arbitrary filters, either search first and delete the matching IDs, or throw.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async deleteDocuments({
    index,
    filters,
  }: SearchTypes.SearchDeleteDocumentsInput): Promise<SearchTypes.SearchTask> {
    await this.client.deleteDocumentsByFilter(index, filters)
    return { index, status: "succeeded" }
  }
}
```

#### Parameters

**deleteDocuments**

- `_input`: [SearchDeleteDocumentsInput](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchDeleteDocumentsInput) — The index and the filters selecting the documents to remove.
  - `index`: `string` — The physical name of the index to delete the documents from.
  - `filters`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters) — The filters selecting the documents to remove. Deleting by ID is a filter on the index's primary key, such as `{ id: ["prod_1", "prod_2"] }`.
    - `$and`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters)[] (optional) — Filters that must all match.
    - `$or`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters)[] (optional) — Filters of which at least one must match.
    - `$not`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters) (optional) — Filters that must not match.
    - `q`: `string` (optional) — The free-text query. Sits among the filters so a `query.graph` call converts to `query.search` unchanged; the module lifts it out before compiling the rest, so a provider never sees `q` as a field.

#### Returns

**deleteDocuments**

- `Promise`: Promise<[SearchTask](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchTask)> — The write's task.
  - `id`: `string` (optional) — The ID identifying the write in the search engine, which is passed back to the provider's `waitForTask` method. It's set only for a deferred write, since a provider applying writes inline has nothing to identify.
  - `index`: `string` (optional) — The name of the index the write was applied to.
  - `status`: [SearchTaskStatus](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchTaskStatus) — The write's status.
  - `error`: `object` (optional) — The error that made the write fail, if its `status` is `failed`.
    - `message`: `string` — The error's message.
    - `code`: `string` (optional) — The error's code, as reported by the search engine.

### deleteIndex

This method deletes an index and everything in it. The Search Module calls it
to clean up an old version of an index once a newer one has taken over.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async deleteIndex({
    index,
  }: {
    index: string
  }): Promise<SearchTypes.SearchTask> {
    await this.client.deleteIndex(index)
    return { index, status: "succeeded" }
  }
}
```

#### Parameters

**deleteIndex**

- `_input`: `object` — The index to delete.
  - `index`: `string` — The index's physical name.

#### Returns

**deleteIndex**

- `Promise`: Promise<[SearchTask](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchTask)> — The write's task.
  - `id`: `string` (optional) — The ID identifying the write in the search engine, which is passed back to the provider's `waitForTask` method. It's set only for a deferred write, since a provider applying writes inline has nothing to identify.
  - `index`: `string` (optional) — The name of the index the write was applied to.
  - `status`: [SearchTaskStatus](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchTaskStatus) — The write's status.
  - `error`: `object` (optional) — The error that made the write fail, if its `status` is `failed`.
    - `message`: `string` — The error's message.
    - `code`: `string` (optional) — The error's code, as reported by the search engine.

### listIndexes

This method lists the indexes you hold. The Search Module reads the document counts to
spot an index that lost its data and needs reseeding.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async listIndexes(): Promise<SearchTypes.SearchIndexInfo[]> {
    const indexes = await this.client.listIndexes()

    return indexes.map((index) => ({
      name: index.uid,
      provider: MySearchProviderService.identifier,
      document_count: index.numberOfDocuments,
    }))
  }
}
```

#### Returns

**listIndexes**

- `Promise`: Promise<[SearchIndexInfo](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchIndexInfo)[]> — The indexes and their document counts.
  - `SearchIndexInfo[]`: [SearchIndexInfo](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchIndexInfo)[]
    - `name`: `string` — The index's physical name.
    - `provider`: `string` — The identifier of the provider holding the index.
    - `document_count`: `number` — The number of documents in the index. The Search Module uses it to spot an index that lost its data and needs reseeding.
    - `created_at`: `Date` (optional) — The date the index was created.
    - `updated_at`: `Date` (optional) — The date the index was last updated.

### search

This method runs a search against an index. The Search Module will use this method in
its `search` and `searchMany` methods.

The free-text query arrives as `q`, already lifted out of `filters`, and
`attributes_to_retrieve` is already narrowed to the fields the index can return.

Compile `input.filters` to your engine's filter syntax, and reject the
operators it can't express rather than approximating them. Also, use
`input.index.physical_name` as the index to query, not `input.index.name`,
since the two differ under an index prefix or between versions.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async search(
    input: SearchTypes.ProviderSearchQuery
  ): Promise<SearchTypes.SearchResult> {
    const response = await this.client.search(input.index.physical_name, {
      query: input.q,
      limit: input.pagination?.take,
    })

    return {
      hits: response.hits.map((hit) => ({ id: hit.id, document: hit })),
      metadata: {
        skip: input.pagination?.skip ?? 0,
        take: input.pagination?.take ?? 20,
        count: response.total,
      },
    }
  }
}
```

#### Parameters

**search**

- `_input`: [ProviderSearchQuery](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.ProviderSearchQuery) — The query, the resolved index definition, and the attributes to return.
  - `index`: [ResolvedSearchIndexDefinition](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.ResolvedSearchIndexDefinition) — The resolved definition of the index to query. Use its `physical_name` as the index to query, since it differs from the index's name under an index prefix or between versions.
    - `name`: `string` — The index's unique name, which is what `query.search({ entity })` resolves against.
    - `entity`: `string` — The `query.graph` entrypoint used to hydrate non-indexed fields.
    - `fields`: `Record<string, [SearchFieldDefinition](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchFieldDefinition)>` — The fields the index holds, keyed by their path in the document.
    - `events`: `string`[] (optional) — Events related and that can affect the data for this index.
    - `consume`: (`event`: [Event](https://docs.medusajs.com/references/types/EventBusTypes/types/types.EventBusTypes.Event)<any>, `context`: [SearchIngestionContext](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchIngestionContext)) => Promise<[SearchMutation](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchMutation)[]> (optional) — Executed on event ingestion to determine the action that needs to be performed on the index.
    - `seed`: (`context`: [SearchSeedContext](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchSeedContext)) => AsyncIterable<[SearchMutation](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchMutation)[]> — Yields mutations in batches — the same shape `consume` returns, so a seed can express a delete, not just an upsert. Ran when there is no data in the index, on reindex, and for the catch-up pass after a full seed.
    - `primary_key`: `string` — The field whose value keys the index's documents.
    - `provider`: `string` — The identifier of the provider backing this index.
    - `settings`: [SearchIndexSettings](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchIndexSettings) — The settings applied to the index.
    - `definition_hash`: `string` — A hash of the definition, which the module compares to detect that an index drifted from its definition and must be migrated.
    - `physical_name`: `string` — The root physical index name, derived from `name` and the module's `index_prefix`. Never queried directly: each version of this index gets its own physical index derived from this root, and the module resolves which one is currently active before reading or writing.
  - `attributes_to_retrieve`: `string`[] — The field paths the search engine must return on every hit. Already narrowed by the Search Module to the fields the index can serve, so project it as given.
  - `q`: `string` (optional) — Lifted out of `filters` by the module, because `filters` compiles to a DSL with no representation for free text.
  - `filters`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters) (optional) — The filters to apply, including the free-text query as `q`.
    - `$and`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters)[] (optional) — Filters that must all match.
    - `$or`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters)[] (optional) — Filters of which at least one must match.
    - `$not`: [SearchFilters](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFilters) (optional) — Filters that must not match.
    - `q`: `string` (optional) — The free-text query. Sits among the filters so a `query.graph` call converts to `query.search` unchanged; the module lifts it out before compiling the rest, so a provider never sees `q` as a field.
  - `pagination`: [SearchPagination](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchPagination) (optional) — How the results are paginated and sorted.
    - `skip`: `number` (optional) — The number of documents to skip before the returned hits. Mutually exclusive with `cursor`.
    - `take`: `number` (optional) — The maximum number of hits to return.
    - `order`: `Record<string, [SearchOrderBy](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchOrderBy)>` (optional) — The fields to sort the hits by, keyed by the field's dotted path. The reserved `_score` key sorts by relevance.
    - `cursor`: `string` (optional) — An opaque provider cursor, as returned in a previous result's `metadata.next_cursor`. Mutually exclusive with `skip`.
  - `search_options`: [SearchOptions](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchOptions) (optional) — The options changing how the query is matched, scored, and aggregated.
    - `attributes_to_search_on`: `string`[] (optional) — The dotted paths of the fields to match the free-text query against. Defaults to every field marked `searchable` on the index.
    - `match_strategy`: [SearchMatchStrategy](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchMatchStrategy) (optional) — How query terms combine. - `"all"` (default): every term must appear as a complete token. - `"any"`: at least one term must match. - `"last"`: typeahead. Completed terms must match in full; the last term is a prefix, so `"my sear"` matches `"My search results"`.
    - `typo_tolerance`: `boolean` (optional) — Whether to match terms that are misspelled by a character or two. it is ignored unless the query includes a free-text `q` and the searched fields have typo tolerance enabled in the index's `settings.typo_tolerance`.
    - `facets`: (`string` \| [SearchFacetRequest](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFacetRequest))[] (optional) — The facets to compute alongside the hits. A string is shorthand for a `value` facet on that field.
    - `disjunctive_facets`: `boolean` (optional) — Compute each facet ignoring the filter on that same field, so a storefront keeps showing sibling values of an active filter. Needs one query per facet on every engine reviewed, so the module expands them and hands the set to `provider.searchMany`.
    - `highlight`: `boolean` \| [SearchHighlightOptions](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchHighlightOptions) (optional) — How the matched terms are highlighted in the returned hits. Applied only when the query includes a free-text `q`; otherwise it is ignored. `true` highlights every field the query searches on. Pass an object to pick fields, tags, or snippet cropping.
    - `distinct`: `string` (optional) — Return at most one hit per distinct value of this field.
    - `min_score`: `number` (optional) — Discard hits scoring below this threshold.
    - `include_score`: `boolean` (optional) — Whether to return each hit's relevance score.
    - `locales`: `string`[] (optional) — Query-time language hint, e.g. `["en"]`. Engines that analyze per language (Meilisearch, Algolia) use it to pick the analyzer; a provider that cannot honour it rejects it rather than silently matching differently. Neither first-party provider does: configure the analyzer language on the provider (postgres) or on the field (Medusa) instead.
    - `vector`: [SearchVectorOptions](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchVectorOptions) (optional) — The options of a vector, or semantic, search to run instead of, or alongside, the free-text query.
    - `count`: [SearchCountStrategy](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchCountStrategy) (optional) — How the total number of matching documents is computed. `"exact"` may be rejected or slow depending on the provider.
    - `provider_options`: `Record<string, Record<string, unknown>>` (optional) — Escape hatch for engine features the interface does not model, keyed by provider identifier, e.g. `{ typesense: { drop_tokens_threshold: 0 } }`.
  - `context`: [QueryContextType](https://docs.medusajs.com/references/types/CommonTypes/types/types.CommonTypes.QueryContextType) (optional) — The context passed to the `query.graph` call during hydration.

#### Returns

**search**

- `Promise`: Promise<[SearchResult](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchResult)<Record<string, unknown>>> — The hits, any facets, and the metadata.

### searchMany

This method runs multiple queries in a single request to the search engine.
The Search Module uses it for its `searchMany` method, including the extra
queries produced by disjunctive faceting.

The default runs `search` concurrently. Override it to pack the queries into
one engine round-trip.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async searchMany(
    inputs: SearchTypes.ProviderSearchQuery[]
  ): Promise<SearchTypes.SearchResult[]> {
    const { results } = await this.client.multiSearch(
      inputs.map((input) => ({
        indexUid: input.index.physical_name,
        query: input.q,
      }))
    )

    - `facets`: (`string` \| [SearchFacetRequest](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchFacetRequest))[] (optional) — The facets to compute alongside the hits. A string is shorthand for a `value` facet on that field.
    - `disjunctive_facets`: `boolean` (optional) — Compute each facet ignoring the filter on that same field, so a storefront keeps showing sibling values of an active filter. Needs one query per facet on every engine reviewed, so the module expands them and hands the set to `provider.searchMany`.
    - `highlight`: `boolean` \| [SearchHighlightOptions](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchHighlightOptions) (optional) — How the matched terms are highlighted in the returned hits. Applied only when the query includes a free-text `q`; otherwise it is ignored. `true` highlights every field the query searches on. Pass an object to pick fields, tags, or snippet cropping.
    - `distinct`: `string` (optional) — Return at most one hit per distinct value of this field.
    - `min_score`: `number` (optional) — Discard hits scoring below this threshold.
    - `include_score`: `boolean` (optional) — Whether to return each hit's relevance score.
    - `locales`: `string`[] (optional) — Query-time language hint, e.g. `["en"]`. Engines that analyze per language (Meilisearch, Algolia) use it to pick the analyzer; a provider that cannot honour it rejects it rather than silently matching differently. Neither first-party provider does: configure the analyzer language on the provider (postgres) or on the field (Medusa) instead.
    - `vector`: [SearchVectorOptions](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchVectorOptions) (optional) — The options of a vector, or semantic, search to run instead of, or alongside, the free-text query.
    - `count`: [SearchCountStrategy](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchCountStrategy) (optional) — How the total number of matching documents is computed. `"exact"` may be rejected or slow depending on the provider.
    - `provider_options`: `Record<string, Record<string, unknown>>` (optional) — Escape hatch for engine features the interface does not model, keyed by provider identifier, e.g. `{ typesense: { drop_tokens_threshold: 0 } }`.
  - `context`: [QueryContextType](https://docs.medusajs.com/references/types/CommonTypes/types/types.CommonTypes.QueryContextType) (optional) — The context passed to the `query.graph` call during hydration.

#### Returns

**searchMany**

- `Promise`: Promise<[SearchResult](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchResult)<Record<string, unknown>>[]> — A result for each query, in the same order as the queries.
  - `SearchResult<Record<string, unknown>>[]`: [SearchResult](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchResult)<Record<string, unknown>>[]

### upsertDocuments

This method adds documents to an index, replacing any that already exist under the same
ID. The Search Module uses it both for direct writes and for seeding, where it's called
once per batch.

If your engine applies writes later rather than inline, return a task with an `id` and
implement `waitForTask`, so the module can wait before making a new version active.

Write to `input.index` but read schema information from `input.definition`:
while a new version is being seeded, `input.index` is that version's
physical index, whereas the definition is that of the logical index.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async upsertDocuments({
    index,
    definition,
    documents,
  }: {
    index: string
    definition: SearchTypes.ResolvedSearchIndexDefinition
    documents: SearchTypes.SearchDocument[]
  }): Promise<SearchTypes.SearchTask> {
    const task = await this.client.addDocuments(index, documents, {
      schema: definition.fields,
    })
    return { id: `${task.uid}`, index, status: "enqueued" }
  }
}
```

#### Parameters

**upsertDocuments**

- `_input`: `object` — The documents to write.
  - `index`: `string` — The index's physical name. This is the index to write to.
  - `definition`: [ResolvedSearchIndexDefinition](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.ResolvedSearchIndexDefinition) — The definition of the logical index the documents belong to. Use it for schema information, such as the index's `fields` or `primary_key`.
    - `name`: `string` — The index's unique name, which is what `query.search({ entity })` resolves against.
    - `entity`: `string` — The `query.graph` entrypoint used to hydrate non-indexed fields.
    - `fields`: `Record<string, [SearchFieldDefinition](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchFieldDefinition)>` — The fields the index holds, keyed by their path in the document.
    - `events`: `string`[] (optional) — Events related and that can affect the data for this index.
    - `consume`: (`event`: [Event](https://docs.medusajs.com/references/types/EventBusTypes/types/types.EventBusTypes.Event)<any>, `context`: [SearchIngestionContext](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchIngestionContext)) => Promise<[SearchMutation](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchMutation)[]> (optional) — Executed on event ingestion to determine the action that needs to be performed on the index.
    - `seed`: (`context`: [SearchSeedContext](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchSeedContext)) => AsyncIterable<[SearchMutation](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchMutation)[]> — Yields mutations in batches — the same shape `consume` returns, so a seed can express a delete, not just an upsert. Ran when there is no data in the index, on reindex, and for the catch-up pass after a full seed.
    - `primary_key`: `string` — The field whose value keys the index's documents.
    - `provider`: `string` — The identifier of the provider backing this index.
    - `settings`: [SearchIndexSettings](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchIndexSettings) — The settings applied to the index.
    - `definition_hash`: `string` — A hash of the definition, which the module compares to detect that an index drifted from its definition and must be migrated.
    - `physical_name`: `string` — The root physical index name, derived from `name` and the module's `index_prefix`. Never queried directly: each version of this index gets its own physical index derived from this root, and the module resolves which one is currently active before reading or writing.
  - `documents`: [SearchDocument](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchDocument)[] — The documents, each with an `id`.
    - `id`: `string`

#### Returns

**upsertDocuments**

- `Promise`: Promise<[SearchTask](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchTask)> — The write's task.
  - `id`: `string` (optional) — The ID identifying the write in the search engine, which is passed back to the provider's `waitForTask` method. It's set only for a deferred write, since a provider applying writes inline has nothing to identify.
  - `index`: `string` (optional) — The name of the index the write was applied to.
  - `status`: [SearchTaskStatus](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchTaskStatus) — The write's status.
  - `error`: `object` (optional) — The error that made the write fail, if its `status` is `failed`.
    - `message`: `string` — The error's message.
    - `code`: `string` (optional) — The error's code, as reported by the search engine.

### upsertIndex

This method brings an index in line with its definition, creating it if it doesn't
exist. The Search Module calls it for every definition when migrations run.

You may recreate the index if your engine can't alter a schema in place. That's safe:
the module only points this at an index it's about to seed, never at one that has to
keep serving reads, and never during a partial rebuild.

Throw if the definition asks for something your engine can't hold, such as a
facet type it doesn't support. Since migrations run before the application
serves requests, the error surfaces at startup rather than as wrong results
later.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async upsertIndex({
    index,
  }: {
    index: SearchTypes.ResolvedSearchIndexDefinition
  }): Promise<SearchTypes.SearchTask> {
    await this.client.createIndex(index.physical_name, {
      primaryKey: index.primary_key,
    })

    return { index: index.physical_name, status: "succeeded" }
  }
}
```

### waitForTask

This method waits until a deferred write is applied. The Search Module uses it
to wait for a seed to be applied before making the new version active.

Implement it if your engine acknowledges writes and applies them later. When
it's not implemented, the module assumes a write is applied once
`upsertDocuments` resolves.

#### Example

```ts
class MySearchProviderService extends AbstractSearchProviderService {
  // ...
  async waitForTask(
    task: SearchTypes.SearchTask,
    options?: { timeout_ms?: number }
  ): Promise<SearchTypes.SearchTask> {
    const result = await this.client.waitForTask(task.id!, {
      timeOutMs: options?.timeout_ms,
    })

    return {
      ...task,
      status: result.status === "succeeded" ? "succeeded" : "failed",
    }
  }
}
```

#### Parameters

**waitForTask**

- `task`: [SearchTask](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchTask) — The task returned by the write, holding the `id` that identifies it.
  - `id`: `string` (optional) — The ID identifying the write in the search engine, which is passed back to the provider's `waitForTask` method. It's set only for a deferred write, since a provider applying writes inline has nothing to identify.
  - `index`: `string` (optional) — The name of the index the write was applied to.
  - `status`: [SearchTaskStatus](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchTaskStatus) — The write's status.
  - `error`: `object` (optional) — The error that made the write fail, if its `status` is `failed`.
    - `message`: `string` — The error's message.
    - `code`: `string` (optional) — The error's code, as reported by the search engine.
- `options`: `object` (optional) — The options of the wait.
  - `timeout_ms`: `number` (optional) — How long to wait for the task before giving up, in milliseconds.

#### Returns

**waitForTask**

- `Promise`: Promise<[SearchTask](https://docs.medusajs.com/references/types/SearchTypes/interfaces/types.SearchTypes.SearchTask)> — The task in its final state.
  - `id`: `string` (optional) — The ID identifying the write in the search engine, which is passed back to the provider's `waitForTask` method. It's set only for a deferred write, since a provider applying writes inline has nothing to identify.
  - `index`: `string` (optional) — The name of the index the write was applied to.
  - `status`: [SearchTaskStatus](https://docs.medusajs.com/references/types/SearchTypes/types/types.SearchTypes.SearchTaskStatus) — The write's status.
  - `error`: `object` (optional) — The error that made the write fail, if its `status` is `failed`.
    - `message`: `string` — The error's message.
    - `code`: `string` (optional) — The error's code, as reported by the search engine.

## 3. Create Module Provider Definition File

Create the file `src/modules/my-search/index.ts` with the following content:

```ts title="src/modules/my-search/index.ts"
import MySearchProviderService from "./service"
import { 
  ModuleProvider, 
  Modules
} from "@medusajs/framework/utils"

export default ModuleProvider(Modules.SEARCH, {
  services: [MySearchProviderService],
})
```

This exports the module provider's definition, indicating that the `MySearchProviderService` is the module provider's service.

---

## 4. Use Module Provider

To use your Search Module Provider, add it to the `providers` array of the Search Module in `medusa-config.ts`:

> **Note**
>
> If you're using more than one Search Module Provider, make sure to set the `default_provider` option of the Search Module to the provider you want to use by default. You can also set it in an index definition's `provider` property to use a specific provider for that index.

```ts title="medusa-config.ts"
module.exports = defineConfig({
  // ...
  modules: [
    {
      resolve: "@medusajs/medusa/search",
      options: {
        // Only needed with more than one provider.
        // default_provider: "my-search",
        providers: [
          {
            // if module provider is in a plugin, use `plugin-name/providers/my-search`
            resolve: "./src/modules/my-search",
            id: "my-search",
            options: {
              // provider options...
            },
          },
          // ...
        ],
      },
    },
  ],
})
```


---

## 5. Test it Out

To test the module out, add an API route that uses `query.search` to search through products. For example, create the file `src/api/search-products/route.ts` with the following content:

```ts title="src/api/search-products/route.ts"
import {
  MedusaRequest,
  MedusaResponse,
} from "@medusajs/framework/http"

export const GET = async (
  req: MedusaRequest,
  res: MedusaResponse
) => {
  const query = req.scope.resolve("query")

  const { data, search_result } = await query.search({
    entity: "product",
    fields: ["id", "title", "handle"],
    filters: {
      q: req.query.q as string,
      status: "published",
    },
    pagination: { take: 20 },
  })

  res.json({
    products: data,
    metadata: search_result.metadata,
  })
}
```

This route resolves the [Query](!docs!/learn/fundamentals/module-links/query) from the [Medusa container](!docs!/learn/fundamentals/medusa-container) and uses its `search` method to search the `product` index. `query.search` uses your Search Module Provider under the hood to run the query, then hydrates the returned hits with `query.graph`.

Finally, start your Medusa application:

```bash npm2yarn
npm run dev
```

Then, send a request to the route:

```bash
curl "http://localhost:9000/search-products?q=shirt"
```

You'll receive the products whose titles match the query, ordered by relevance, based on your Search Module Provider's implementation:

```json title="Example Response"
{
  "products": [
    {
      "id": "prod_01KXR3J9J610DT161E2E4ZS6P1",
      "title": "Medusa T-Shirt",
      "handle": "t-shirt"
    }
  ],
  "metadata": {
    "skip": 0,
    "take": 20,
    "count": 1,
    "query": "shirt",
    "processing_time_ms": 9
  }
}
```
