 Derived fields are not indexed but are computed dynamically by retrieving values from the `_source` field or doc values. Thus, they can be slow to execute. To improve performance, try the following:

 - Consider using a [`prefilter_field`](#prefilter-field) to automatically prune the search space without explicit filters in the search request.
