Speaking with someone who is new to computers and especially to Google, it seems people believe the search engine answers questions. What it really does is search. Specifically, if you type a question in to Google it is going to search for anywhere on the web that has that question. The difference between these two can be so small as to be semantics except sometimes it's a huge difference.

If you asked Google “Who is the Prime Minister of the UK?” it would start by looking for pages that had that exact question in – so you're likely to first see lots of people on discussion boards or political websites asking this. Not necessarily answering it, either.

Whereas, if you searched instead for the answer, Google would look for pages that had the answer. Follow: search for the words “The Prime Minister of the UK is…” and you'll get every article that includes this sentence.

It is always better to search for the answer than to unknowingly be searching for the question because it is always more useful and sometimes it is gigantically more likely to get you what you want.

Mind you, be careful. If you start typing something like “The Prime Minister of the UK is….” into Google, it might autocompete your search with some choice words.
