I use Infinispan 4.1.0.CR3 and Hibernate-Search 3.1.1.GA, I use Infinispan-lucene-directory to store index. When I use "LOCAL", "replication", "invalidation" mode, infinispan-query works normally, but when I switch to "distribution" mode infinispan-query doesn't index the cache region, and the "getDirectory()" function of "DirectoryProvider" just be called when initialize the directory provider.

First, I want to confirm if Infinispan-Query supports Distribution Mode. I open the ClusteredCacheTest.java of the unit test of infinispan-query 4.1.0.CR3. I change the "createCacheManagers()" function to use the Distribution Mode, that means :

change this line

    "Configuration cacheCfg = getDefaultClusteredConfig(REPL_SYNC);"
to

    "Configuration cacheCfg = getDefaultClusteredConfig(DIST_SYNC);"

also change the import, from

    "import static org.infinispan.config.Configuration.CacheMode.REPL_SYNC;"

to

    "import static org.infinispan.config.Configuration.CacheMode.DIST_SYNC;"

And, when I run the unit test, it fails :

Failed tests:

So, that means the Infinispan-Query doesn't support Distribution Mode by now. If I'm correct?

Second, if it did, how can I set up infinispan-lucence-directory to put index into a cluster? That means if the cache region I need to index is Distribution Mode, the "indexLocalOnly" is true or false? And if I set up a cache region, for example name "indexRegion", to store index, if I can set up this region as Distribution Mode? and how can infinispan-query handle multithread IndexWriter problem from a cluster perspective?

If any body can help me, thanks.
