I tried searching for canceled in the Desperate Housewives forum and got many replies, obviously most or all from other shows. If I search for "canceled Desperate Housewives" then of course that will not work for finding discussions in the Desperate Housewives forum with canceled in the title.
I heard that Desperate Housewives is canceled but tv.com says it is not. I wanted to search for news about that. The news tab for a show of course shows all news stories, not just news about the show.
Unless I am missing something, the web site's search feature is still very primitive.
I realize that this subject has probably been discussed before, but I obviously do not have confidence in the ability to find previous discussions. And believe me, I am someone that does multiple searches for material in other sites every day.
