Searches by date

You know what I’d like to see google (or some other search engine) do? A huge percentage of my searches are for things like “best dvd player under $100”, “desktop editing software suggestions”, and the like. These are queries that most likely will get the best results from forum or blog posts. When I search for them I get the most popular but what I really want is the one that is the newest (and popular). Many of the ‘most popular’ search results are 2-4 years old and that’s not helpful to me at all when I’m looking to buy something. There needs to be a way to search by date.
