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-]*$.

• collectionName string Required

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

• databaseName string Required

  Human-readable label that identifies the database that contains the collection with one or more Atlas Search indexes.

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.

    • extracting words
    • removing punctuation
    • removing accents
    • changing to lowercase
    • removing common words
    • reducing words to their root form (stemming)
