Keep it simply

What Is  was basicly designed to give you the meaning of a definition (or acronym) or a quick bio over a person’s live.  That should be reflected by your search term – only enter the word you want the meaning for or only enter the name of the person you’re interrested in.

Don’t use phrases, fill words or whole sentences.  Don’t type “what is XY” but just “XY”.

Oh, and for those lazy people out there – you don’t even have to type, just talk to your phone!
