Subject Re: Large index question
Date Fri, 13 Oct 2006 20:18:43 GMT
Hello Scott!

I think your index is just not large really. My Sharehound's indexes of my
corporate LAN is about 10G/10mlns of (really small) documents now, and queries
get really little time, less than a second for non-sorted queries and some more
for sorted. The machine is some P4 with 1G RAM. I use just FSDir.

Best regards,

SS> Supposed I want to index 500,000 documents (average document size is
SS> 4kBs).  Let's assume I create a single index and that the index is
SS> static (I'm not going to add any new documents to it).  I would guess
SS> the index would be around 2GB.
