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)
