I think you need a database, not Lucene - especially since you are
not even using any text !

Hi,
Thanks for your previous mail.
Now I changed the configuration to use merging factor 50. I also
disabled
the compound file parameter.
I still have the search problem I had before, now search takes
around 750
msecs for a small set of documents.
[java] Total Query Processing time (msec) : 38745
[java] Total No. of Documents : 7,500,000
[java] Total No. of Executed queries : 50.0
[java] Execution time per query : 774.9 msec
The index is optimized and its size is 830 MB.
Each document has the following terms :
VSID(integer), data(float), type(short int) , precision (byte).
The queries are generate in a loop similar to one below :
loop ...
RangeFilter rq1 = new
RangeFilter("data",”+5.43243243440000”,”+5.43243243449999”true,true);
RangeFilter rq2 = new RangeFilter
("precision",”+0001”,”+0002”,true,true);
ChainedFilter cf = new ChainedFilter(new
Filter[]{rq2,rq1},ChainedFilter.AND);
Query query = qp.parse("type:0");
Hits hits = searcher.search(query,cf);
end loop
I would like to know if there exist any solution to improve the
search
time ? (I need to insert more than 500 million of these data pages
into
lucene)
Thanks,
AliS

 1. The search time for simple queries such as precision:\+0002 is
really high (4-10 seconds). I want to know if this search time is
normal
 2. The search gives TooManyClauses exception when I'm searching
for a
 data item with the queries similar to the one below :
Please see the FAQ at http://wiki.apache.org/jakarta-lucene/
LuceneFAQ:
Why am I getting a TooManyClauses exception?
How do I speed up searching?
If that doesn't help, please re-post you question on the user list.
Regards
Daniel
