Subject Re: IndexSearcher.doc thread safe problem
Date Thu, 10 Jul 2014 02:05:30 GMT

: 4. Syncronized searcher.doc method call in multi-thread(like this: public
: synchronized Document getValue( IndexSearcher searcher, int docId ) {
: return searcher.doc( docId ); })
:     ==> every execution is same.
:            but If I use this method, It is no difference with single thread
: performance.
: What do you think about it?

You're asking us about the behavior of IndexSearcher.doc from 
multi-threaded code, but you haven't shown us enough code to even guess as 
to what your problem might be -- let alone reproduce it.

can you please submit a cully self contained program -- that builds an 
index and then searches it -- and which demonstrates the problem you are 
having?   That way folks trying to help you will have actual code they can 
run on their machine to understand the problem you are describing.
