I do so much searching in the Play Store on a daily basis that every little trick that helps surface relevant results faster and filter out things I don't want is worth its weight in gold. Sometimes, you're searching for XYZ, which you know should be in the title, but instead get a ton of results back with XYZ in the description. This is especially frustrating when a new app or game gets released, and Google hasn't figured out it's popular yet. In that case, it's more than likely that searching for the name of the app will show it somewhere near the last results page.
