I just tried to search for something, and wanted to return results from the last 6 months, but this no longer seems to be possible - the only time filter options were in minutes or hours! This is frustrating, because if you don't restrict by time you can get zillions of results, in no logical order.
It would be helpful if it were at least possible to order the results by time, with most recent first, but this isn't possible either. I was searching for a school name and only wanted recent posts.
