I am working on adding another instance, the new demo is down. Will restart it soon.

The new demo is back online.

Although this time it has 3 instances, adds another ~300K documents and host ~1 million documents in total (almost the entire MSE), I find when I copy some search result and query it, I cannot find the same result again... This is a little wired. Also, both Sil and Martin R have mentioned two queries where the new one can find better results, but even I have almost entire MSE indexed this time, it cannot find the mentioned better results neither.

I am wondering there may be some bugs, let me take some time to find out why.

Anyway, what I have online here at here (temporary link), is a search cluster with 2 machines and 3 instances of searcher (it returns 300 results per query). And it does not require very expensive machine to query entire MSE with a practical latency.

I will look into the search results problem later, now I have to handle some other tasks.
