I thought someone said previously that nntp/news searching under windows does

IMHO Sun E420/E450's will give you the best performance, however do you need
that much power is the question...
Currently I run 2 engines - A news engine and a web engine...
The news engine runs off a P Pro 200 Compaq Deskpro with 64M RAM running Linux
Mandrake 8.0... it returns results under 10 seconds even when busy... this time
increases to 30 seconds when indexing large batches of new news.... this is the
reason why I wrote a news listener which passes the news to the local filesystem
and the indexer as it arrives, it then auto splits the news. The idea being that
it will keep the server from busying itself up.... I will post that code to the
developers when I have finished it completely and when I have got rid of the
bugs...Currently it is running but occasionally fails.
The web search engine has 400,000+ documents and it running on a Sparc U10,
1x440M processor with 1G RAM... results are returned in under 2 seconds
regardless of whether it is indexing/splitting or busy.

You should not have problems but run the *NIX version and take out support with
the developers.
