# Medusa Search API Settings

In this guide, you'll learn about the settings and options that [Medusa Search](../page.mdx) supports on indexes, fields, and queries.

Aside from the fields and settings that every [index definition](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions) declares, Medusa Search supports settings and options of its own.

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).

## Index Settings

Set the `settings` property of an index definition to configure how Medusa Search treats the whole index.

For example:

```ts title="src/search/product.ts"
export const productIndex = defineSearchIndex({
  name: "product",
  entity: "product",
  fields: search.define({
    id: search.keyword().filterable(),
    title: search.text().searchable(),
    brand: search.keyword().filterable(),
  }),
  settings: {
    distinct_attribute: "brand",
    provider_options: {
      "search-medusa": {
        distance_metric: "cosine_distance",
      },
    },
  },
  async *seed({ container }) {
    // ...
  },
})
```

The example declares two settings for the `product` index to control result deduplication and provider-specific options.

Medusa Search accepts the following index settings:

- distinct\_attribute: (\`string\`) The dotted path of a field that Medusa Search deduplicates hits by, returning at most one hit per distinct value. A query that passes its own \`distinct\` search option overrides it.
- provider\_options: (\`object\`) The settings of a specific search engine, keyed by the provider's identifier. Medusa Search reads the \`search-medusa\` entry and ignores the rest.

  - search-medusa: (\`object\`) The settings that only Medusa Search understands.

    - distance\_metric: (\`"cosine\_distance"\` \\| \`"euclidean\_squared"\`) The metric that vector search uses to compare embeddings. \`cosine\_distance\` compares the direction of two embeddings while ignoring their magnitude, which suits normalized embeddings from a text model. \`euclidean\_squared\` compares their straight-line distance, so magnitude counts. A \[vector field]\(#field-options) can override it for itself.
- typo\_tolerance: (\`object\`) The thresholds Medusa Search applies when it matches a misspelled term, and the fields it must never fuzzy-match. Refer to \[Typo Tolerance]\(#typo-tolerance) for an example.

  - enabled: (\`boolean\`) Whether Medusa Search builds a fuzzy index for the index's searchable fields. Set it to \`false\` to keep the index smaller when no query needs typo tolerance.

  - min\_word\_size\_for\_one\_typo: (\`number\`) The shortest term length that tolerates a single typo.

  - min\_word\_size\_for\_two\_typos: (\`number\`) The shortest term length that tolerates two typos. It can't be lower than \`min\_word\_size\_for\_one\_typo\`.

  - disabled\_on\_attributes: (\`string\[]\`) The dotted paths of the fields that must always match exactly, such as a SKU or a serial number where a single character changes the meaning.

The example above sets `distinct_attribute` and `provider_options`. The section below covers `typo_tolerance`, which has a few properties of its own.

### Typo Tolerance

Medusa Search matches misspelled terms with a fuzzy index that it builds on every searchable field by default, so an index tolerates typos without declaring any setting. A query is the opposite: it matches terms exactly until you opt in, as explained in [Opt a Query Into Typo Tolerance](#opt-a-query-into-typo-tolerance).

Set the `typo_tolerance` index setting to change the thresholds Medusa Search applies, to exempt a field, or to turn the fuzzy index off:

```ts title="src/search/product.ts"
export const productIndex = defineSearchIndex({
  name: "product",
  entity: "product",
  fields: search.define({
    title: search.text().searchable(),
    sku: search.keyword().searchable(),
  }),
  settings: {
    typo_tolerance: {
      min_word_size_for_one_typo: 6,
      min_word_size_for_two_typos: 9,
      disabled_on_attributes: ["sku"],
    },
  },
  async *seed({ container }) {
    // ...
  },
})
```

The example tolerates a typo on a term of six characters or more, two typos from nine characters, and never fuzzy-matches `sku`. Refer to [Index Settings](#index-settings) for every property the setting accepts.

#### Opt a Query Into Typo Tolerance

The setting only prepares the index. Every query matches terms exactly until you pass the [`typo_tolerance` search option](https://docs.medusajs.com/learn/fundamentals/query/search#search-options):

```ts
const { data } = await query.search({
  entity: "product",
  fields: ["id", "title"],
  filters: { q: "sweatshrit" },
  search_options: {
    typo_tolerance: true,
  },
})
```

Medusa Search ranks a fuzzy match below every exact match, so enabling the option adds results rather than reordering the ones you already had.

The option only widens a term match, so Medusa Search ignores it when the query passes no `q` filter, or when none of the fields it searches has a fuzzy index.

***

## Field Options

Use a field's [`providerOptions()`](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions/modifiers#provideroptions) modifier to configure how Medusa Search indexes that field.

For example:

```ts title="src/search/product.ts"
export const productIndex = defineSearchIndex({
  fields: search.define({
    title: search.text().searchable().providerOptions({
      "search-medusa": {
        glob: true,
      },
    }),
    // ...
  }),
  // ...
})
```

Medusa Search reads the following field options:

- full\_text\_search: (\`boolean\` \\| \`object\`) The full-text search configuration of a searchable field. Pass \`true\` to keep the defaults, or an object to change how Medusa Search tokenizes the field, such as its language. Refer to \[Set a Field's Language]\(#set-a-fields-language) for an example.

  - language: (\`string\`) The language Medusa Search analyzes the field with, in lowercase. It decides the stemmer and the stop-word list the field uses, and it applies only when you also enable \`stemming\` or \`remove\_stopwords\`. Refer to \[Set a Field's Language]\(#set-a-fields-language) for the languages it accepts.

  - stemming: (\`boolean\`) Whether Medusa Search reduces a term to its stem, so a query for \`banken\` also matches \`bank\`. It stems the field in the language that \`language\` names, so set both together.

  - remove\_stopwords: (\`boolean\`) Whether Medusa Search drops the language's common words, such as \`de\` in Dutch, from the field and from a query that searches it. Arabic, Greek, Romanian, Tamil, and Turkish have no stop-word list.

  - ascii\_folding: (\`boolean\`) Whether Medusa Search strips accents, so a query for \`muller\` matches \`müller\`. Enable it for a language written in Latin script with diacritics, such as French or Spanish.

  - case\_sensitive: (\`boolean\`) Whether Medusa Search keeps the case of a term, so a query only matches a term written the same way.

  - max\_token\_length: (\`number\`) The longest term Medusa Search indexes from the field, in bytes, between \`1\` and \`254\`. It drops anything longer, which keeps a field of long identifiers from growing the index.
- glob: (\`boolean\`) Whether Medusa Search can wildcard-match the field's exact value, which the \`$prefix\` and \`$like\` filters need. Medusa Search always omits it on the \`id\` field.
- regex: (\`boolean\`) Whether Medusa Search can match the field with a regular expression.
- ann: (\`boolean\` \\| \`object\`) The approximate nearest neighbor configuration of a \[vector field]\(!resources!/infrastructure-modules/search/index-definitions/fields#searchvector). Pass \`true\` to keep the defaults, or an object to override the index's metric for this field.

  - distance\_metric: (\`"cosine\_distance"\` \\| \`"euclidean\_squared"\`) The metric that vector search uses for this field. \`cosine\_distance\` compares the direction of two embeddings while ignoring their magnitude, which suits normalized embeddings from a text model. \`euclidean\_squared\` compares their straight-line distance, so magnitude counts.

### Set a Field's Language

Medusa Search matches a searchable field term by term, and it doesn't stem those terms until you ask it to. Set the field's `language` along with `stemming` so a query matches the other forms of a word, which matters for a catalog whose titles and descriptions aren't in English.

For example, to analyze a Dutch title and a German one:

```ts title="src/search/product.ts"
export const productIndex = defineSearchIndex({
  name: "product",
  entity: "product",
  fields: search.define({
    id: search.keyword().filterable(),
    title_nl: search.text().searchable().providerOptions({
      "search-medusa": {
        full_text_search: {
          language: "dutch",
          stemming: true,
          remove_stopwords: true,
        },
      },
    }),
    title_de: search.text().searchable().providerOptions({
      "search-medusa": {
        full_text_search: {
          language: "german",
          stemming: true,
          remove_stopwords: true,
        },
      },
    }),
  }),
  async *seed({ container, catchup, last_key: lastKey }) {
    const batchSize = 200
    let cursor = lastKey

    while (true) {
      const { data: products } = await container.query
        .graph({
          entity: "product",
          fields: [
            "id",
            "title",
            "updated_at",
            "deleted_at",
          ],
          filters: {
            ...(catchup
              ? { updated_at: { $gte: catchup.since } }
              : {}),
            ...(cursor ? { id: { $gt: cursor } } : {}),
          },
          pagination: {
            take: batchSize,
            order: { id: "ASC" },
          },
          withDeleted: !!catchup,
        })

      if (!products.length) {
        return
      }

      const live = products.filter((p) => !p.deleted_at)
      const gone = products.filter((p) => !!p.deleted_at)
      const ids = live.map((p) => p.id)

      const [nlTitles, deTitles] = await Promise.all(
        ["nl-NL", "de-DE"].map(async (locale) => {
          const { data } = await container.query.graph({
            entity: "product",
            fields: ["id", "title"],
            filters: { id: ids },
          }, { locale })

          return new Map(
            data.map((p) => [p.id, p.title])
          )
        })
      )

      yield [
        ...(live.length
          ? [{
              action: "upsert" as const,
              documents: live.map((product) => ({
                id: product.id,
                title_nl:
                  nlTitles.get(product.id) ?? product.title,
                title_de:
                  deTitles.get(product.id) ?? product.title,
              })),
            }]
          : []),
        ...(gone.length
          ? [{
              action: "delete" as const,
              filters: { id: gone.map((p) => p.id) },
            }]
          : []),
      ]

      if (products.length < batchSize) {
        return
      }

      cursor = products[products.length - 1].id
    }
  },
})
```

The `seed` function reads each page of products once per locale with Query's `locale` option, then writes each locale's title to its own field. It falls back to the product's stored title when a locale has no translation. It also pages by ID so an interrupted run resumes, and yields a `delete` write for the products the [catch-up pass](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions#handle-the-catch-up-pass) finds deleted.

A Dutch query for `banken` now matches a product whose title holds `bank`, and a German query for `stühle` matches `Stuhl`.

### Supported Languages in Medusa Search

Medusa Search stems the following languages:

- `arabic` (no stop-word list)
- `danish`
- `dutch`
- `english`
- `finnish`
- `french`
- `german`
- `greek` (no stop-word list)
- `hungarian`
- `italian`
- `norwegian`
- `portuguese`
- `romanian` (no stop-word list)
- `russian`
- `spanish`
- `swedish`
- `tamil` (no stop-word list)
- `turkish` (no stop-word list)

`remove_stopwords` has no effect on the languages marked above with `(no stop-word list)`. For a language written in Latin script with diacritics, such as French or Spanish, also set `ascii_folding` so a query without the accents still matches.

A field holds one language, since it holds one string. To search a catalog in more than one market, declare a field per locale as explained in [Search Text in Multiple Locales](https://docs.medusajs.com/resources/infrastructure-modules/search/index-definitions/fields#search-text-in-multiple-locales), then pass the `attributes_to_search_on` search option to search the field of the shopper's locale.

Configure the language on the index's fields rather than per query. Medusa Search rejects a query that passes the `locales` search option.

***

## Search Query Options

Pass `provider_options` to [query.search options](https://docs.medusajs.com/learn/fundamentals/query/search#search-options) to change how Medusa Search runs that query.

For example:

```ts
const { data } = await query.search({
  entity: "product",
  fields: ["id", "title"],
  filters: { q: "sweatshirt" },
  search_options: {
    provider_options: {
      "search-medusa": {
        consistency: "eventual",
      },
    },
  },
})
```

Medusa Search reads one query option, `consistency`, which accepts the following values:

- consistency: (\`"strong"\` \\| \`"eventual"\`) How current the index must be for this query. \`strong\` searches every write made before the query started, so the query reflects a write you made moments ago. \`eventual\` skips that check and can miss the latest writes, which makes the query faster.
