Optimize will release disk space if have lots of delete. (Merge will do same
thing).
For me, I think optimize will little bit speed up search.
Which JRE are you using? for windows, if you are using 64bit JRE, then
lucene try to map index to memory.
that will use lots of memory and also involve lot
it always add one more search conditional.
like you search by subject:hello.
the back end will search
subject:hello AND accound:齐保元

Doron,
To verify actual query speed, i think you may need:

2) in solrconfig.xml, set filterCache and queryResultCache value to 0
3) restart solr
4) run the query and check the qtime result
That may give you some idea what is actual query time.
To break down query time, yo
