If it is still being worked, you cannot fail with Google. I very rarely use the built in search on the forums since I find Google to be so much more accurate.
There are also little syntaxes that can help searches such as the following:
Search the keyword, with no exceptions (does not separate every word in the phrase):
"Hi my name is bill" - Search with quotes will bring up hits with the quoted phrase located in the link.
Blahblah site: vbforums.mmobay.net - Searches "blahblah" excluding all hits except vbforums.mmobay.net.
These little tools will really narrow results and allow you to accurately track users, posts.
