docs: This will find all documents in the collection that match the specified example object.
  
              Note: the limit attribute is not supported on sharded collections. Using it will result in an error.
              The options attributes waitForSync and limit can given yet without an ecapsulation into a json object.
              But this may be deprecated in future versions of arango
  
              Returns result dict of the request.
  
              :param collection Collection instance
              :param example_data An example document that all collection documents are compared against.
  
              :param wait_for_sync  if set to true, then all removal operations will instantly be synchronised to disk.
              If this is not specified, then the collection's default sync behavior will be applied.
  
              :param limit an optional value that determines how many documents to replace at most. If limit is
              specified but is less than the number of documents in the collection, it is undefined which of the
              documents will be replaced.
