Just because the search button is there doesn't mean the site will run slowly.
Its when one or more people do a search it can slow a forum down.
The PF datadase is HUGE! Now If one or more people decide to do a few searchs thing of all the information it will slow the site down bigtime!
A good way around this is to have an "offline" database.
Searchs are quieried in the offline database - and not the current one with all the quality, highly informativve posts in it
at say 3am every morning the offline database gets update with the current pf database - ok so there will be a 24hour delay in finding recent posts, but surley this wouldn't cause a problem as any recent topics people are looking for should be about one or two pages down?
Just an Idea like, and would take a lot of strain off the server when peeps search for "Cossie"
