dropSearchIndex
Definition
New in version 7.0: (Also available starting in 6.0.7)
Deletes an existing Atlas Search index.
The mongosh method db.collection.dropSearchIndex()
provides a wrapper around the updateSearchIndex database command.
Important
This command can only be run on a deployment hosted on MongoDB Atlas, and requires an Atlas cluster tier of at least M10.
Syntax
Command syntax:
db.runCommand(    {       dropSearchIndex: "<collection name>",       id: "<index Id>",       name: "<index name>"    } ) 
Command Fields
The dropSearchIndex command takes the following fields:
Field  | Type  | Necessity  | Description  | 
|---|---|---|---|
  | string  | Required  | Name of the collection that contains the index to delete.  | 
  | string  | Conditional  | 
 You must specify either the   | 
  | string  | Conditional  | Name of the index to delete. You must specify either the   | 
Behavior
After you run the dropSearchIndex command, there may be a delay between when you
receive a response from the command and when the index is deleted.
To see the status of your search indexes, use the
$listSearchIndexes aggregation stage. Once your index is
deleted, that index no longer appears in the $listSearchIndexes
output.
Access Control
If your deployment enforces access control, the user running
the dropSearchIndex command must have the dropSearchIndex privilege
action on the database or collection:
{    resource: {       db : <database>,       collection: <collection>    },    actions: [ "dropSearchIndex" ] } 
The built-in dbAdmin and readWrite roles provide
the dropSearchIndex privilege. The following example grants the
readWrite role on the qa database:
db.grantRolesToUser(    "<user>",    [ { role: "readWrite", db: "qa" } ] ) 
Output
A successful dropSearchIndex command returns the following:
{    ok: 1 } 
Example
The following example deletes a search index named searchIndex01 on
the contacts collection:
db.runCommand( {    dropSearchIndex: "contacts",    name: "searchIndex01" } )
