Return All User-Defined Analyzers for One Cluster

GET /api/atlas/v1.0/groups/{groupId}/clusters/{clusterName}/fts/analyzers

Returns all Atlas Search custom analyzers that the specified cluster uses in the specified project. Custom analyzers define the operations to perform to index a field. To use this resource, the requesting Service Account or API Key must have the Project Data Access Read Write role.

Custom Analyzers

Path parameters

groupId string Required

Unique 24-hexadecimal digit string that identifies your project. Use the /groups endpoint to retrieve all projects to which the authenticated user has access.

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.

Format should match the following pattern: ^([a-f0-9]{24})$.
clusterName string Required

Name of the cluster that contains the collection with one or more Atlas Search indexes.

Format should match the following pattern: ^[a-zA-Z0-9][a-zA-Z0-9-]*$.

Query parameters

envelope boolean

Flag that indicates whether Application wraps the response in an envelope JSON object. 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. Application adds the status parameter to the response body.

Default value is false.
pretty boolean

Flag that indicates whether the response body should be in the prettyprint format.

Default value is false.

Prettyprint
