@Voline This is sensible, and I'm sure I recall a time when Twitter worked like this too. You could search for #Anonymous and it would bring up tweets about the hacktivist movement. Then at some point they changed it, so a search for that hashtag brought up random tweets using "anonymous" in other contexts, making the search useless. There must be other examples of this, like brand names that are also common words. Hashtagging is a deliberate act which should be reflected in search results.
