- (dict) –
  
  A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.
  
  Note
  Currently, wildcards are not supported in filters.

    - (string) –
MaxRecords (integer) –
