GG replies to a member hgaving trouble searching by enclosing the search query in quotes.

Very weird. I'd doublecheck the query, reboot your computer, try with a different browser, rig up a web form and test it, or try a different search engine--briefly, of course ;) . I just tried a search with quotes and it worked fine. It's also possible that you've got some scumware on your machine intercepting queries and not escaping them correctly. So you might want to run spybot--never hurts to check for spyware periodically anyway. Let us know if you figure it out, or write to help [at] google.com if it persists..
