This is a similar point to the one I was going to make. A search engine input gives you a blank slate. Sometimes you have a nebulous idea of what you need to know but don't know how that fits into the source, so blank slate searching becomes clumsy and hit & miss. FAQs conversely give direction and clarification so can run the dual role of guiding and forming what the user is trying to search as well as being an end point or gateway to the actual knowledge they seek. This kind of orientation can be valuable if the language of a site is heavily domain based.
