Yes, here a while back, I started to go through some of my albums (small chunck by small chunk) and started to convert the information in the Composer field from the generally standard _"T. Shakur/J. Jackson"_ and such, into full names & Stage Names to end up like _"Tupac Amaru Shakur (2Pac)/Johnny Jackson (Johnny J)"_
Now, I'm fairly new to MP3Tag, so go easy on me here, but earlier I loaded up my main folder which contains all my Artist & Album subfolders and wanted to quickly find the albums I have already edited into that format, so I figured an easy filter on the Composer field of _" ("_ would do the trick, as they are the only ones with _()'s_ in that field. But when doing so, it returns no results. Does the filter just not work with _(_ & _)_ or, what? Any help is appreciated.

You have to 'escape' some special characters with the slash character (see help file), so use '**(**' for '**(**' and '**)**' for '**)**'.
Literals are all characters except ".", "|", "\*", "?", "+", "(", ")", "{", "}", "[", "]", "^", "$".
These characters are literals when preceded by a "".

Wicked Cool Beans, thanks much for the help. I looked at the Help a few times, but found myself lost each time. I look forward to learning more and unleashing the full power of teh MP3Tag!
