The search engine works very similar to most other ones around on the net, simply type in several words associated with what you're looking for, and it will search the site for any files that contain them! Please keep in mind that the search engine ONLY searches this site, nothing else, so try to limit your searches to something you think you might find here.
The search engine also supports the use of the '+' and '-' operators, to tell it if a word MUST or MUST NOT (respectively) appear on a page; for example, if you were looking for a page about mustangs, but not the airplane, you would type this: "mustang -airplane". If, on the other hand, you were interested in the airplane, and not the horse, you would type "mustang +airplane" or maybe even "mustang +airplane -horse". You may also give the engine an idea of whether something is part of another word by using the '*' operator, to say anything before this (*word) or anything after this (word*) is ok. For example, if you enter buck, the words Starbuck or bucket will have an equal rating; however, if you enter *buck, then Starbuck will be evaluated higher than bucket. If you are looking for a specific phrase, then you can enter it in quotes, for example, "Howard Jones" will only return hits that have those words in the exact sequence, while Howard Jones will return and pages that contain both the words Howard and Jones.
