db.collection.updateSearchIndex()

New in version 7.0: (Also available starting in 6.0.7)

Updates an existing Atlas Search index.

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

Command syntax:

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

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.

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
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
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.

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.

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" } ]
)

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

  1. Create a search index named searchIndex01 on the movies collection:

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

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