Is there an advanced search on the Mac App Store? I'm searching for a particular app. I know its name and the publisher, but when I type them both into the search box in the top right corner, I get no results. If I search for the app name, I get loads of results, but the main page doesn't show the publisher. So it seems that the only way to find the one I want is to click on every result to see who the publisher is until I find the one I'm after. Surely there's a better way?
