How should I configure MoinMoin page text searches to ignore its own help files?

My software team uses a MoinMoin wiki to record our coding guidelines and other best practices. Like most wikis, each page includes a basic search box, and MoinMoin offers both "Titles" and "Text" command buttons. (The former matches page names only and the开发者_JS百科 latter does a full-text search.)

By default, each MoinMoin page's search box returns too much information, because it matches both wiki content and the application's own (voluminous) help pages. Its advanced search page--also called FindPage--can omit help searches via the Exclude underlay checkbox, but we'd like to make that its default behavior. Unfortunately, the engineer who set up our wiki doesn't know how to make that change. How can we limit basic text searches to group content only?

As far as I remember there was an advanced search page, where you could find "Don't search help pages" checkbox. Is this what you're looking for?
