Hi to all 

We using solr multi core with 6 core in shard mode per server (2 server till 
now. therefore totally 12 core). using tomcat on windows 2008 with 18GB RAM 
assign to it.

We add almost 6 million doc per day to solr (up to 200 doc/sec) which must 
appear in query result real-time. (currently more than 350 million doc indexed)
Query very slow (about 4-32 sec).but Update performance very good.

note1: result must sort by publish date desc.
note2: Query on one shard also slow sometime (300ms-2s)
note3: we can't optimize index because always doc add.

Can solr help me? 
if yes, What's best configuration ? 
if not, what is the best solution ?

Kind Regards,
Hamid
