The fts resource allows you to retrieve and edit Atlas Search analyzers and index configurations for the specified cluster.

The Atlas Administration API authenticates using HTTP Digest Authentication. Provide a programmatic API public key and corresponding private key as the username and password when constructing the HTTP request. To learn how to configure API access for an Atlas project, see Get Started with the Atlas Administration API.

Note

Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

For more information about Atlas Search indexes, see What is MongoDB Atlas Search? and Review Atlas Search Index Syntax.

Resource

Base URL: https://cloud.mongodb.com/api/atlas/v1.0

POST /groups/{GROUP-ID}/clusters/{CLUSTER-NAME}/fts/indexes

Note

You cannot create an Atlas Search index on any collection in the admin, local, or config databases in any cluster.

Request Parameters

Request Path Parameters

Path Element	Type	Necessity	Description
`GROUP-ID`	string	Required	Unique identifier for the project that contains the specified cluster.
`CLUSTER-NAME`	string	Required	Name of the cluster that contains the collection on which you want to create an Atlas Search index.

Request Query Parameters

This endpoint may use any of the HTTP request query parameters available to all Atlas Administration API resources. These are all optional.

Name	Type	Necessity	Description	Default
pageNum	integer	Optional	Page number, starting with one, that Atlas returns of the total number of objects.	`1`
itemsPerPage	integer	Optional	Number of items that Atlas returns per page, up to a maximum of 500.	`100`
includeCount	boolean	Optional	Flag that indicates whether Atlas returns the totalCount parameter in the response body.	`true`
pretty	boolean	Optional	Flag that indicates whether Atlas returns the JSON response in the prettyprint format.	`false`
envelope	boolean	Optional	Flag that indicates whether Atlas wraps the response in an envelope. Some API clients cannot access the HTTP response headers or status code. To remediate this, set `envelope=true` in the query. Endpoints that return a list of results use the results object as an envelope. Atlas adds the status parameter to the response body.	`false`

Request Body Parameters

Name	Type	Necessity	Description
`analyzer`	string	Optional	Analyzer to use when creating the index. Defaults to lucene.standard.
`analyzers`	array of BSON objects	Optional	Custom analyzers to use in this index.
`collectionName`	string	Required	Name of the collection the index is on.
`database`	string	Required	Name of the database the collection is in.
`mappings`	object	Required	Object containing index specifications for the collection fields.
`mappings` `.dynamic`	boolean	Conditional	Required if `mappings.fields` is omitted. Indicates whether the index uses dynamic or static mappings. For dynamic mapping, set the value to `true`. For static mapping, specify the fields to index using `mappings.fields`.
`mappings` `.fields`	object	Conditional	Required if `mappings.dynamic` is `false` or is omitted. Object containing one or more field specifications.
`name`	string	Required	Name of the index.
`searchAnalyzer`	string	Optional	Analyzer to use when searching the index. Defaults to lucene.standard.
`synonyms`	array of documents	Optional	Synonyms mapping definition to use in this index.
`synonyms[i]` `.analyzer`	string	Required	Name of the analyzer to use with this synonym mapping. If you set `mappings.dynamic` to `true`, you must use the default analyzer, lucene.standard, here also. Atlas Search doesn't support these custom analyzer tokenizers and token filters in the index definition for synonyms: nGram tokenizer edgeGram tokenizer daitchMokotoffSoundex token filter nGram token filter edgeGram token filter shingle token filter
`synonyms[i]` `.name`	string	Required	Name of the synonym mapping definition. Name must be unique in this index definition and it can't be an empty string.
`synonyms[i]` `.source`	document	Required	Collection details for this synonym mapping definition.
`synonyms[i]` `.source` `.collection`	string	Required	Name of the source MongoDB collection for the synonyms. Documents in this collection must be in the format described in the Synonyms Source Collection Documents.

Response Elements

The HTTP response returns a JSON document with an index definition for the newly created index. An index definition contains the following elements:

Name	Type	Description
`analyzer`	Optional	Analyzer used when creating the index.
`analyzers`	Optional	Custom analyzers used in this index.
`collectionName`	string	Name of the collection the index is on.
`database`	string	Name of the database the collection is in.
`indexID`	string	Unique identifier for the index.
`mappings`	object	Object containing index specifications for the collection fields.
`mappings` `.dynamic`	boolean	Flag indicating whether the index uses dynamic or static mappings.
`mappings` `.fields`	object	Object containing one or more field specifications.
`name`	string	Name of the index.
`searchAnalyzer`	string	Analyzer to use when searching the index.
`status`	string	Status of the index. Value can be one of the following statuses: `IN_PROGRESS` - Atlas is building or re-building the index after an edit. `STEADY` - Index is ready to use. `FAILED` - Atlas could not build the index. `MIGRATING` - Atlas cluster tier is being upgraded and indexes are migrating.
`synonyms`	array of documents	Synonyms mapping definition used in this index.
`synonyms[i]` `.analyzer`	string	Name of the analyzer used in this synonym mapping. If `mappings.dynamic` is `true`, Atlas Search uses the default analyzer, lucene.standard, for synonym mapping.
`synonyms[i]` `.name`	string	Name of the synonym mapping.
`synonyms[i]` `.source`	document	Collection details for this synonym mapping definition.
`synonyms[i]` `.source` `.collection`	string	Name of the source MongoDB collection for the synonyms.
