Is there anyway to search Twitter into the distant past. I'd like to know any occurrence of a term that was ever tweeted. It seems on http://search.twitter.com I can only search like one week at a time.
Topsy can help you find tweets from the distant past by using their advanced search.
This search query find references to Obama in tweets between Jan/2009 & Jan/2011 - http://topsy.com/s?mintime=1254335400&maxtime=1293820200&q=obama
Try http://snapbird.org/ It searches terms/people all the way back to Twitter's inception.
