I don't quite understand what's going on with the "advanced' tab. Sometimes it selects all namespaces; other times it selects some namespaces, and yet other times it selects still different namespaces.  There seems to be no rhyme or reason to which namespaces are selected.  And there's no button to deselect/select all namespaces anymore.  This makes customised searching much harder.

Also, at w:c:tardis, we're trying to exclude a special namespace — Howling and Howling talk — from default searches. It's a part of local policy that this be so, because spoilers are only allowed in this one name space. It's vital that this happen or else contributors won't come to our site while Doctor Who is in season for fear of having their experience ruined. We 'need to make sure that this namespace (okay, these 2 namespaces) absolutely require every single user to intentionally choose to search in those namespaces. Otherwise, people will be spoiled by completely innocent searching.

Because of the inconsistencies with respect to the advanced tab, I literally can't tell what's going on.
