Hi all,
I have index of size 85MB. My query looks as follows:
+(t:boss* d:boss* dd:boss* tg:boss*) +st:act +ntid:0 +cid:1 +dr:[20080410 TO 20081010] +rT:[002 TO 005]
All the fields used in the query are stored in the indexes (Indexed & Stored)
The query response time for me is around 30 seconds when running mutliple simultanoeous threads (~100). The no. of matches is ~30k but I retrieve only the top 100 results. I am using Hibernate Search which is a wrapper around Lucene. I retrieve the "id" filed from the index which is also indexex and stored.
What is the approach that I should take for improving the performance?
Will just indexing the values without storing them work (Index & UnStored)?
My machine configuration is:
P4 2.66GHz 1.99 GB RAM
The code for searching runs in JBoss application server which has a maximum heap size of 1024MB. When these 100 threads are running in the application server the CPU utilization is 100% and JBoss consumes all of the heap size.
Any pointers on index optimization would be really appreciated.

Rakesh Shete
