There are. Several different kinds, in fact. (Apparently there's more 
than one possible regex syntax or something.)

I still don't get why you'd need to do complex searching. And if for 
some strange reason you do need to, why use an obfuscated text string 
with limited processing capabilities when you can use a real programming 
language?
