answer:Yeah, sometimes Twitter doesn’t go back more than a week. Other times, it returns the first 1500 results, however soon those are (so for Trending Topics, it might only go back 5 minutes, for terms less popular, it might go back a few months.) Allow me to suggest Twitter Advanced Search, which goes back to 2008. Make sure to check out the special Twitter search operators, like “since:2009–02-15” or “until:2009–02-15”.
