How do I override what operator is used for a query?#

The member query_operator_to_q_operator for Filter is used to convert from e.g. : to icontains. You can specify another callable here:

    columns__album__filter__query_operator_to_q_operator=lambda op: 'exact',

The above will force the album name to always be looked up with case sensitive match even if the user types album<Paranoid in the advanced query language. Use this feature with caution!

For more advanced customization you can use value_to_q. It is a callable that takes filter, op, value_string_or_f and returns a Q object. The default handles __, different operators, negation and special handling of when the user searches for null.
