It seems that Google is in a experimental mood.
Web 2.0 Central reports that Google tries to grasp a meaning from our queries - and that's a first step to semantic search.
Earlier today I was searching on google and something new popped up. It seems Google was experimenting with some interesting search refinement.
On a search for Apple, it offered a few refinements (as I recall more news, more blogs)
http://www.google.com/search?hl=en&q=apple+more%3Ablogs&btnG=Search
It appended a more:blogs to the search and low and behold the search results had more blogs in them.
