Thanks all! One last question...
If I had a collection of 2.5 billion docs and a demand averaging 200
queries per second, what's the confidence that Solr/Lucene could handle
this volume and execute search with sub-second response times?

Sorry, I meant that it maxed out in the sense that my maxDoc field on
the stats page was 8.8 million, which indicates that the most docs it
has ever had was around 8.8 million. It's down to about 7.8 million
currently. I have seen no signs of a maximum number of docs Solr can
handle.

By maxed out do you mean that Solr's performance became unacceptable
beyond 8.8M records, or that you only had 8.8M records to index? If
the former, can you share the particular symptoms?

My experiences so far with this level of data have been good.
Number of records: Maxed out at 8.8 million
Database size: friggin huge (100+ GB)
Index size: ~24 GB
1) It took me about a day to index 8 million docs using a
non-optimized
program I wrote. It's non-optimized in the sense that it's not
multi-threaded. It batched together groups of about 5,000 docs at a
time
to be indexed.
2) Search times for a basic search are almost always sub-second. If we
toss in some faceting, it takes a little longer, but I've hardly ever
seen it go above 1-2 seconds even with the most advanced queries.
Hope that helps.

I am new to the list and new to lucene and solr. I am considering
Lucene
for a potential new application and need to know how well it scales.
Following are the parameters of the dataset.
Number of records: 7+ million
Database size: 13.3 GB
Index Size: 10.9 GB
My questions are simply:
1) Approximately how long would it take Lucene to index these
documents?
2) What would the approximate retrieval time be (i.e. search response
time)?
Can someone provide me with some informed guidance in this regard?
Thanks in advance,
John
