If you do this, it'd be great to have a way to select the 'mode' of search (exact query vs 'smart' terms). I'm not sure what the user interface ought to be, but "literally" "anything" "would" "be" "better" than the contortions you have to go through to force search engines to search for the terms you've actually provided.

Great job so far, by the way, keep up the good work!
