Vista - Server 2008, new search confusing, no documentation

I am looking for files with string (2) in the file name. The new search
feature works differently than previous versions. Way too many results. I
am getting all files with a 2 in them. Haven't been able to find
documentation on new "features"

I have tried seraching for:

*(2)*.*
"(2)".*

Neither work exactly as I am looking for.

Any help appreciated plus perhaps a link to some documentation on the new
searching "features".

Thanks
