Pursuant to a post I made about some questionable old questions, we need the ability to have Tag Wikis be searchable.
For example, if the Tag Wiki for C++ has a list of books, a user searching for "C++ Books" should see the Tag Wiki page as one of the search items. It should look just like a question (more or less).
It shouldn't just be the preamble text at the top. A new user simply won't notice that; they're conditioned to ignore everything before the first item in the actual list. So the Tag Wiki page needs to appear in the list, with a title of some sort.
