We've only gone to 10 replicated search servers at CNET (and that
number turned out to be way overkill).  For most types of requests, a
single server can handle way more than 3 requests per second.  Much
depends on the types of queries you will be throwing at it, and the
size and nature of your corpus.

Searchers use rsync to pull index changes from the master.
It takes a little work to set up (ssh config, etc), but the upside is
that it's all fairly transparent.
