Sanne Grinovero resolved HSEARCH-754.
-------------------------------------
Resolution: Fixed
> Add configuration options to control maximum size of segments
> -------------------------------------------------------------
>
> Key: HSEARCH-754
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-754
> Project: Hibernate Search
> Issue Type: New Feature
> Components: documentation, engine, optimizer
> Reporter: Sanne Grinovero
> Assignee: Sanne Grinovero
> Fix For: 4.0

>
> org.apache.lucene.index.LogByteSizeMergePolicy exposes configuration settings which are currently not selectable in Hibernate Search:
> - minMergeSize
> - maxMergeSize
> - maxMergeSizeForOptimize
> being able to limit the size of a segment is very useful to get best performance out of the Infinispan Lucene Directory: performance degrades due to the need for readlocks when the size of a segment is higher than the maximum chunk size in Infinispan.
> Readlocks are automatically engaged when needed, so this has no functional impact but is quite noticeable in terms of performance.
