Hi Suman

Here are some of the things we did:

- cache searcher/s
- cache indexreader/s
- all users use the same searchers
- perform a background search when apps starts to warm up search engine
- use numerics where necessary
- use shorter dates (i.e. do you really need a granularity of up to the second?)
- if you have any custom analyzers, optimize them for efficiency

If you have realtime indexes
- cache index readers for a few seconds at a time

Regards,

Jamie

Hi ,


I am also using range based searches for dates .I am converting time  to
utc based seconds format and storing them to indexes. and then running
range queries


Is there something needed to make it more efficient.

Thanks,
Suman
