Otis,
Thanks for the responses; you've nailed it down mostly. Please see my

As for HDDs, people have noted some nice speedups in Lucene using
Solid-state drives, if you can afford them.
I've seen the average response time cut in 5-10 times when switching
to SSD. 64GB SSD is starting at EUR 200 so that can be a lot cheap

Hello,
First, some numbers we're expecting.
- The average size of a doc: ~100K
- The number of indexes: 1
- The query response time we're looking for: < 200 - 300ms
- The number of stored docs:
1st year: 500K - 1M

Matthew,
Thanks, a very good point.

I can't speak to a lot of this - but regarding the servers I'd go with
the more powerful ones, if only for the amount of ram. Your index will
likely be larger than 1 gig, and with only two you'll have a lot of
your index not stored in ram, which will slow down your QPS.
Thanks for your time
