Great idea Peter, certainly gives many more search options/criteria. I've noticed the same thing, it often takes a couple of tries to find what i'm looking for - and that's with something i know is there. My worry would be that others that don't know what they are looking for would give up before they found their answer.
I guess the search function was adequate "in the beginning", but with the variety/volume of posters, topics & posts it's become ineffective.
It certainly would be helpful if the webmaster could replace the existing Search with this one or at least upgrade the existing Search function.
