I think this might be very helpful, i thought it was already implemented, but tried out by myself, and it didn't work, it would be cool if you input a string like:
"John Doe & Jane Doe"

And then it returns only the "John Doe & Jane Doe" results, cause, a lot of times there are irrelevant search results that prevent from finding the actual target of search. i e: if you search for real mccoy there will be results like: andy mccoy - whatever (real version), thanks a lot!. keep the excelent job.
