The product indexes in this guide's snippets are simplified to show one feature at a time. For examples of indexing prices in multiple currencies, option values, categories, and other product data, refer to the [Product Index Examples guide](https://docs.medusajs.com/resources/infrastructure-modules/search/product-index-examples). ## What is a Field Modifier? A modifier declares what the engine can do with a field. For example, `searchable()` includes the field in free-text matching, while `filterable()` allows filtering on it. You can chain multiple modifiers to a field. A modifier that doesn't apply to a type isn't available on it, so an invalid combination fails to compile instead of failing when your application starts. Refer to [Search Index Fields](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions/fields#define-index-fields) for the modifiers each type accepts. Adding, removing, or changing a modifier changes the definition's hash, which the Search Module treats as a schema change. Refer to the [Reindexing and Migrations guide](https://docs.medusajs.com/resources/infrastructure-modules/search/reindexing) to learn how it rebuilds the index. *** ## searchable() Includes the field in free-text matching, which is what the `q` filter passed to `query.search` searches against. Available on `keyword` and `text` fields. A field with no `searchable` modifier is never matched as free text, even when it holds a string. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ title: search.text().searchable(), // ... }), // ... }) ``` Pass a `weight` to boost how much the field contributes to a result's relevance. A field with a higher weight ranks its matches above equally good matches in a lower-weighted field. The weight defaults to `1`, so `searchable()` and `searchable({ weight: 1 })` behave the same. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ title: search.text().searchable({ weight: 3 }), description: search.text().searchable({ weight: 1 }), // ... }), // ... }) ``` In this example, a product matching a query in its title outranks one matching only in its description. - The [PostgreSQL provider](https://docs.medusajs.com/resources/infrastructure-modules/search/providers/postgres) maps the weight onto PostgreSQL's four relevance labels. A weight of `3` or more is the highest label, `2` the next, anything above `1` the next, and `1` or less the lowest. So there are four tiers, and raising a weight past `3` changes nothing. - The [Medusa Search provider available for Cloud users](https://docs.medusajs.com/cloud/search) multiplies the field's relevance by the weight, so a weight of `5` does outrank a weight of `3`. Refer to [Medusa Search vs PostgreSQL](https://docs.medusajs.com/cloud/search/postgres) for the other features providers treat differently. *** ## filterable() Allows [filters](https://docs.medusajs.com/learn/fundamentals/query/search#apply-filters) on the field. Available on every type except `vector`. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ status: search.keyword().filterable(), // ... }), // ... }) ``` Filtering on a field without this modifier throws an error, since the Search Module validates the query against the definition before it reaches the provider. *** ## sortable() Allows ordering results by the field through passing `pagination.order` to `query.search`. Available on every type except `vector`. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ created_at: search.date().sortable(), // ... }), // ... }) ``` *** ## facetable() Allows [facets](https://docs.medusajs.com/learn/fundamentals/query/search#facets) on the field. A facet summarizes the matched documents by that field, which is what a storefront's filter sidebar shows. Available on every type except `vector`. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ brand: search.keyword().facetable(), // ... }), // ... }) ``` A query then requests the facet, and the result carries it in `search_result.facets`, keyed by field name: ```ts const { search_result } = await query.search({ entity: "product", filters: { q: "shirt" }, search_options: { facets: ["brand"] }, }) console.log(search_result.facets) ``` The shape of each entry depends on the kind of facet, as shown in [Facet Types](#facet-types). ### Facet Types By default, the facet type depends on the field's type: - `integer`, `float`, and `date` fields default to `["range"]`. - `stats` is never a default. Add it explicitly, since it's the least widely supported kind and implying it would make numeric fields unusable on a provider without aggregations. - Every other type defaults to `["value"]`. You can also pass `types` to `facetable()` to choose which kinds of facet the field allows. Only `integer`, `float`, and `date` accept the `types` option. For example: ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ age: search.float().facetable({ types: ["value"], }), // ... }), // ... }) ``` Each kind returns a different shape: - `value`: the distinct values of the field and how many documents hold each one. It can also return `other_count` for documents falling outside the returned values. ```json title="Example Value Facet" { "brand": { "type": "value", "values": [ { "value": "acme", "count": 12 }, { "value": "borg", "count": 4 } ] } } ``` - `range`: how many documents fall into each bucket the query defines. The result echoes each bucket's `key`, `from`, and `to` with its `count`. Only available on the `integer`, `float`, and `date` field types. ```json title="Example Range Facet" { "min_price": { "type": "range", "ranges": [ { "key": "cheap", "to": 50, "count": 9 }, { "key": "mid", "from": 50, "to": 200, "count": 21 } ] } } ``` - `stats`: one aggregate summary of the field across the matched documents, rather than a breakdown. Only available on the `integer`, `float`, and `date` field types. ```json title="Example Stats Facet" { "min_price": { "type": "stats", "min": 10, "max": 450, "avg": 92.5, "sum": 3700, "count": 40 } } ``` `avg` and `sum` are optional, since not every engine reports them. Requesting a facet kind the field doesn't allow throws an error. Passing a field name as a string, such as `facets: ["min_price"]`, requests a `value` facet, so it fails on a numeric field that only allows `range`. *** ## retrievable() Whether the field comes back on a hit. Most fields are retrievable by default, so you can omit this modifier unless you want to turn it off. Available on every type. A `vector` field is the exception: it defaults to not retrievable, since a list of hundreds of numbers is rarely useful to the caller. Chain `retrievable()` on one to get the embedding back on every hit. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ search_blob: search.text().searchable().retrievable(false), // ... }), // ... }) ``` A field that isn't retrievable still counts toward matching. `query.search` reads this modifier to decide which requested fields the engine can serve, and which it must fetch with `query.graph`. An `object` field's container is never retrievable, since the index only stores the sub-fields you declared. Request those sub-fields by their dotted path, such as `brand.name`, rather than requesting `brand`. *** ## array() Marks the field as holding a list of its type, rather than one value. Available on every type except `vector`. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ tags: search.keyword().array().filterable().facetable(), // ... }), // ... }) ``` A filter on an array field matches when any element matches. Faceting on one counts a document once per distinct element. *** ## embed() Asks [Medusa Search](https://docs.medusajs.com/cloud/search) to create the field's embedding from text your documents pass on that same field, rather than having your documents supply the embedding. Available on a `vector` field only. `embed()` takes no arguments: ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ title: search.text().searchable(), title_embedding: search.vector(1536).embed(), // ... }), // ... }) ``` With `embed`, your documents pass a string on the vector field, and a query can search it by passing raw text as `search_options.vector.query`. Refer to [Let Medusa Search Create the Embedding](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions/fields#let-medusa-search-create-the-embedding) for the full details. `embed` is a [Medusa Search](https://docs.medusajs.com/cloud/search/semantic-search) feature, available for Cloud projects on the Enterprise plan. *** ## providerOptions() Pass provider-specific options for one field, keyed by provider identifier. Use it to reach a feature the field definition doesn't model. Available on every type. ```ts title="src/search/product.ts" import { defineSearchIndex, search, } from "@medusajs/framework/utils" export const productIndex = defineSearchIndex({ fields: search.define({ title: search.text().searchable().providerOptions({ "search-medusa": { glob: true, }, }), // ... }), // ... }) ``` The options are passed to the targeted provider only, so you can pass different options to different providers for the same field. An option only does something if the provider consumes it. A provider that doesn't read the `providerOptions` modifier ignores whatever you pass, so check the provider's documentation for the options it accepts. Of the providers Medusa ships, the [Medusa Search provider available for Cloud users](https://docs.medusajs.com/cloud/search) is the only one that reads them, and its [guide lists the full set](https://docs.medusajs.com/cloud/search/settings#field-options). These options are separate from the options you set for a provider in `medusa-config.ts`. Those configure the provider itself, whereas these travel with the index definition and apply to one field. --- The best way to deploy Medusa is through Medusa Cloud where you get autoscaling production infrastructure fine tuned for Medusa.
