Subject Range Queries Performance Hit
Date Thu, 25 Mar 2010 11:07:40 GMT
Hello,


Range queries are lowering down the performance of search.
I am using date in my clucene application .

lucene doc has these kind of fields:

startdt="1242758400" enddt="1241980500"



now when i am searching for
searchingdate = new RangeQuery(lastyear time in seconds,current time in
seconds, true);

searchingdate1 = new RangeQuery(current time in seconds,nextyear time in
seconds, true);

Query :i want all doc , created after last year and expired before next year.

but the query is taking 15ms to run.
if i remove the query the execution time is reduced to half.

1. any other thing that i can use for range queries
2. converting the time to minutes is also not helping me.

Help me with the solution.


Thanks,
Suman
