# analyzer
<important>
  Only [`text`](https://www.elastic.co/elastic/docs-builder/docs/2532/reference/elasticsearch/mapping-reference/text) fields support the `analyzer` mapping parameter.
</important>

The `analyzer` parameter specifies the [analyzer](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2532/manage-data/data-store/text-analysis/anatomy-of-an-analyzer) used for [text analysis](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2532/manage-data/data-store/text-analysis) when indexing or searching a `text` field.
Unless overridden with the [`search_analyzer`](https://www.elastic.co/elastic/docs-builder/docs/2532/reference/elasticsearch/mapping-reference/search-analyzer) mapping parameter, this analyzer is used for both [index and search analysis](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2532/manage-data/data-store/text-analysis/index-search-analysis). See [Specify an analyzer](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2532/manage-data/data-store/text-analysis/specify-an-analyzer).
<tip>
  We recommend testing analyzers before using them in production. See [Test an analyzer](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2532/manage-data/data-store/text-analysis/test-an-analyzer).
</tip>

<tip>
  The `analyzer` setting can **not** be updated on existing fields using the [update mapping API](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-put-mapping).

## `search_quote_analyzer`

The `search_quote_analyzer` setting allows you to specify an analyzer for phrases, this is particularly useful when dealing with disabling stop words for phrase queries.
To disable stop words for phrases a field utilising three analyzer settings will be required:
1. An `analyzer` setting for indexing all terms including stop words
2. A `search_analyzer` setting for non-phrase queries that will remove stop words
3. A `search_quote_analyzer` setting for phrase queries that will not remove stop words
