You've just pressed one of my language-independent style hot buttons. Why on earth are you using an if/then/else here? What's wrong with the straightforward:
return "" == results
The expression results in a boolean, and it's even the one you want to return. So why not return it?
Minor nitpick since we are on 'begginers' list: you need parenthesis there, so either return ("" == results) or return $ "" == results otherwise it would get parsed as '(return "") == results'. Also, note that instead of doing "" ==, you could use 'null', so return (null results) HTH, -- Felipe.
