If you want to copy all links with a specified text as part 
of the URL (like www.foo.com/bar.shtml?q=t-hawk), yes, this 
is possible, using scan rules:
+*t-hawk*

But if you want to catch all pages containing the word 't-
hawk', no, this feature isn't yet implemented!

This might be done in the future, anyway
