Basic idea behind this effort is to change search engine into a platform. Current implementation is just a start to show how it can be achieved. There is lot of scope for improvement with your feedback.
Don't get limited by what capabilities current platform provides. We can improve it with your feedback.
First reaction you will have after seeing this is "It is average search engine. Why would I ever use it." Answer to that question is, at present it is technology demostrator. Even without support of any content providers or any other backing, I developed it myself such that it can support most of your search needs. Consider this as baseline with rapid scope for improvement.
