Thread:Project:Support desk/Search function?

Is there an extension or mod, which allows you to search for, say, the letter "T", which will return every page that begins with the letter "T"? Or something which allows you to view every page that exists in the wiki - a sort of wiki map?

We need something like this to find orphaned pages, and to detect spam.
