Filter with reg expression

Just wondering, is it possible to filter using regex? I can't seem to find how if it is possible. also is it possible to filter case sensative?

Thanks.

To use regular expression use i.e.
artist MATCHES

or for all tag fields and file name
* MATCHES

case sensitive is only possible with regular expression, i.e.
artist MATCHES (?-i)

thanks that works :slight_smile:
