Identify bottleneck associated with not pooling searchers
---------------------------------------------------------
Key: LUCENE-1265
URL: https://issues.apache.org/jira/browse/LUCENE-1265
Project: Lucene - Java
Issue Type: Task
Components: Search
Reporter: Karl Wettin
There have been multiple reports suggesting synchronization problems due to
great search performace boost while pooling searchers under heavy load.
I think this should be confirmed. Then identified and fixed, alternatively add
such a pool to the code base.

Use one instance of IndexSearcher.
Share a single IndexSearcher across queries and across threads in your
application.
