db.collection.updateSearchIndex()

Important

This command can only be run on a deployment hosted on MongoDB Atlas, and requires an Atlas cluster tier of at least M10.

Important

mongosh Method

This page documents a mongosh method. This is not the documentation for database commands or language-specific drivers, such as Node.js.

For the database command, see the updateSearchIndex command.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

For the legacy mongo shell documentation, refer to the documentation for the corresponding MongoDB Server release:

mongo shell v4.4

Syntax

Command syntax:

db.<collection>.updateSearchIndex(
   <name>,
   {
      <definition>
   }
)

Command Fields

updateSearchIndex() takes these fields:

Field	Type	Necessity	Description
`name`	string	Required	Name of the search index to update.
`definition`	document	Required	Document that describes the updated index definition. For details on `definition` syntax, see Search Index Definition Syntax.

Search Index Definition Syntax

The search index definition takes the following fields:

{
   analyzer: "<analyzer-for-index>",
   searchAnalyzer: "<analyzer-for-query>",
   mappings: {
      dynamic: <boolean>,
      fields: { <field-definition> }
   },
   analyzers: [ <custom-analyzer> ],
   storedSource: <boolean> | {
      <stored-source-definition>
   },
   synonyms: [ {
      name: "<synonym-mapping-name>",
      source: {
         collection: "<source-collection-name>"
      },
      analyzer: "<synonym-mapping-analyzer>"
   } ]
}

Field	Type	Necessity	Description
`analyzer`	string	Optional	Specifies the analyzer to apply to string fields when indexing. If you omit this field, the index uses the standard analyzer.
`searchAnalyzer`	string	Optional	Specifies the analyzer to apply to query text before the text is searched. If you omit this field, the index uses the same analyzer specified in the `analyzer` field. If you omit both the `searchAnalyzer` and the `analyzer` fields, the index uses the standard analyzer.
`mappings`	object	Optional	Specifies how to index fields on different paths for this index.
`mappings.dynamic`	boolean	Optional	Enables or disables dynamic field mapping for this index. If set to `true`, the index contains all fields containing supported data types. If set to `false`, you must specify individual fields to index using `mappings.fields`. If omitted, defaults to `false`.
`mappings.fields`	document	Conditional	Required only if dynamic mapping is disabled. Specifies the fields to index. To learn more, see Define Field Mappings.
`analyzers`	array	Optional	Specifies the Custom Analyzers to use in this index.
`storedSource`	boolean or Stored Source Definition	Optional	Specifies document fields to store for queries performed using the returnedStoredSource option. You can store fields of all Data Types on Atlas Search. The `storedSource` value can be one of these: `true`, to store all fields `false`, to not store any fields An object that specifies the fields to `include` or `exclude` from storage If omitted, defaults to `false`. To learn more, see Define Stored Source Fields in Your Atlas Search Index.
`synonyms`	array of Synonym Mapping Definitions	Optional	Specifies synonym mappings to use in your index. Configuring synonyms allows you to you index and search for words that have the same or a similar meaning. To learn more, see Define Synonym Mappings in Your Atlas Search Index.

Behavior

updateSearchIndex() triggers an index build with the new index definition. There may be a delay between when you receive a response from the command and when the updated index is ready.

The old index definition can still support queries while the new index is being built. Once the new index finishes building, the old index is no longer usable. To see the status of your search indexes, use the $listSearchIndexes aggregation stage.

Access Control

If your deployment enforces access control, the user running updateSearchIndex() must have the updateSearchIndex privilege action on the database or collection:

{
   resource: {
      db : <database>,
      collection: <collection>
   },
   actions: [ "updateSearchIndex" ]
}

The built-in readWrite and restore roles provide the updateSearchIndex privilege. The following example grants the readWrite role on the qa database:

db.grantRolesToUser(
   "<user>",
   [ { role: "readWrite", db: "qa" } ]
)

Example

The following example creates a new Atlas Search index and then updates that index.

Create a search index named searchIndex01 on the movies collection:

db.movies.createSearchIndex(
   "searchIndex01",
   {
      mappings: { dynamic: true },
      storedSource: {
         exclude: [ "imdb.rating" ]
      }
   }
)

Update the searchIndex01 index:

db.movies.updateSearchIndex(
   "searchIndex01",
   {
      mappings: { dynamic: true },
      storedSource: {
         exclude: [ "movies" ]
      }
   }
)
