Just want to let you know that there are two search functions here.

1. The forum search function on the top navigation bar.

2. Google search function at the bottom of every forum page.

You may find that the Google search function works better since you can all of the special Google search functions to narrow down your search.

You can find out more about the Google advanced search functions here: http://www.google.com/intl/en/help/refinesearch.html
