Writing Search URLs with Boolean Operators
 

I'm trying to figure out how to manually write vBulletin urls to create direct links to selected searches. I found this thread, which is very helpful and is exactly what I want to do. The only problem is that thread doesn't explain how to include boolean operators such as "NOT" and "AND". Of course, all I see is "searchid=" when I use the built in search engine so I can't copy/paste and not all sites construct their search parameters the same way.

Can anyone tell me what I need to write in the url to use boolean operators for vBulletin?
