Twitter revamps search engine
"Subtle" is a good word to describe New Twitter's new search function, but improvement is improvement. The "real-time information network" announced recently that they have changed the architectural way in which their search platform makes queries to their systems database.
The new functionality scales better and can index more Tweets per second, all while using less system resources. The new program is no longer using MySQL queries.
