Your screenshot is a little blurry, but it looks to me like you have an open quote at the beginning of your search bar example. Assuming you have a close quote at the end, the search is only going to look for the exact phrase "Importing a MySQL schema to Xcode as a CoreData Data Model," so it's not surprising that you only get one result. You're not using the quotes in your title search, and you have lots of juicy programming-related words, so it's not surprising that you get many results there.
The main issue here is that the search bar searches everything, not just the title — though it was changed to weight the title more heavily at one point for exactly this reason — while the Ask Question bar searches only in the title.
I am against any proposal which would remove users' ability to search question bodies and answers, which is effectively what this proposal is (though I do realize that wasn't the intent of the request).
