planCacheClearFilters

New in version 2.6.

Removes index filters on a collection. Although index filters only exist for the duration of the server process and do not persist after shutdown, you can also clear existing index filters with the planCacheClearFilters command.

Specify the query shape to remove a specific index filter. Omit the query shape to clear all index filters on a collection.

The command has the following syntax:

copy

db.runCommand(
   {
      planCacheClearFilters: <collection>,
      query: <query pattern>,
      sort: <sort specification>,
      projection: <projection specification>
   }
)

The planCacheClearFilters command has the following field:

Field	Type	Description
planCacheClearFilters	string	The name of the collection.
query	document	Optional. The query predicate associated with the filter to remove. If omitted, clears all filters from the collection. The values in the query predicate are insignificant in determining the query shape, so the values used in the query need not match the values shown using planCacheListFilters.
sort	document	Optional. The sort associated with the filter to remove, if any.
projection	document	Optional. The projection associated with the filter to remove, if any.

Required Access

A user must have access that includes the planCacheIndexFilter action.
