I tried BearShare on W%^$&* and I run Gtk-Gnutella on Linux. I like the latter better but can't seem to figure out how to filter results i.e. how to use regex. If someone has any insight on this please help me.
Thanks.

[Regular expressions]

[If someone has any insight on this please help me. Thanks. ]

Well, although I have some insight into regular expressions, these matter would be far too complicated to discuss here.

But for a starter I can offer some web pages where you will find more information:

http://etext.lib.virginia.edu/helpsheets/regex.html
http://sitescooper.org/tao_regexps.h...larExpressions
http://py-howto.sourceforge.net/regex/regex.html

I hope this will help a bit.
