Twitter doesn't want to find what was written in it about two weeks ago.
Sometimes makes a search of Google on the site (site:twitter.com), but not always.
Tweets themselves – they are guaranteed not removed, they can be viewed.
Is there a normal way to search content of tweets? And then have in a situation when you remember that information (even among those whom you thefollower) took place, but it is impossible to find. To read all the tweets, even for a week for a very long time.
