Twitter’s search tools might be nice, however it does not really leave me wanting more.  Rather than it, I have turned towards Topsy.  If you want to know what other people are tweeting about, sharing with friend or anything else this search engine is the best of the best. 

Rather than indexing documents and content, Topsy does things differently.  It instead shows you the who, what, when, where and how when it comes to search terms out there.

You can easily sort search results by month, week, day, hour or choose to show them all.  You see the top authors on Twitter about that topic, the results themselves and how often they have been shared around.  The more something has been tweeted about, the higher rankings it gets.  You can also pull up results by user – here is my own Topsy page as an example:  http://topsy.com/twitter/mitchkeeler

Overall, I would say Topsy does Twitter search right.  Rather than shifting through junk, you get the best real-time results.  Give them a shot over at Topsy.com.
