A lot of times you really have to know what you are searching for to pull it up. For instance, if I was searching for the name of something, it may never pop up unless I actually searched using the name. But if I knew that I wouldn't need to search....it's a vicious cycle. I have seen people post to someone about using search, and they showed the number of hits they got, yadda yadda, but they used a term in their search that someone searching for that particular thing might not know yet.
