I work online daily and search non-stop and would like to see a feature that allows a person to select a date or time range for the results that show up. Example: Last 30 days, Last 6 months, Last year, etc. A lot of times I'm searching for the most recent data concerning a search. I found this site a few months back and recently read in TechCrunch that you're getting a lot of users migrating from google to duckduckgo. Cheers.
I attached an example screen shot and before you bash it, I understand it looks like Googles feature but how many ways can you really create an original version of something like this. As long as you have the date range option it could look like anything.
