People need to learn how to search. And not just typing in one word and giving up. Think about keywords and try different combos to limit the search. Take a few minutes and research at least a little. It is a common problem at many websites (forums, userboards, etc) and this site. There is a lot of information on this website and the internet in general. There is a lot of data available and your question/concern might have already been addressed. Duplicate questions just add clutter and even more search results to sort through. This applies to search with google and any websites search function.
Here is an easy start. The advanced button on google....
Look at that site and think like those advanced options questions.
