-----------------------------------------
I can confirm it's mostly a documentation patch, setting the JVM environment
properties is enough to enable them. Needs some performance tests? My laptop-local little
index couldn't tell me the difference performance-wise between the three types.

Key: HSEARCH-275
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-275
Project: Hibernate Search
Issue Type: Improvement
Reporter: Sanne Grinovero
Assignee: Sanne Grinovero
Fix For: 3.2.0.CR1
# LUCENE-753: Added new Directory implementation org.apache.lucene.store.NIOFSDirectory,
which uses java.nio's FileChannel to do file reads. On most non-Windows platforms,
with many threads sharing a single searcher, this may yield sizable improvement to query
throughput when compared to FSDirectory, which only allows a single thread to read from an
open file at a time.
