It's not really what I would like to search, but really how I would like to search. Adding filters or restrictions is becoming very important to me. For example, I want to search google and I don't want my search results to return any stackoverflow copy cats, or I'd like to be able to group my results by something (e.g. domain, relevance, date, etc). Also, I'd like to specify what to search (e.g. search title only, h1 only, body only, etc..)
