Hi,

Trying to cope with the extreme slowliness of put() operation with indexing [1], I've tried to use the MassIndexer, to create the index AFTER adding all the data in the grid. This actually works pretty well, but, when running in a "single node" grid, it "breaks" the search, which always returns 0 result to any kind of query.

I've modified one of the test suite of InfiniSpan to reproduce the issue:

https://github.com/rpelisse/infinispan/tree/mass-indexer-breaks-search-with-mono-instance

Once this branch is checked out, just run :

$ cd ./query
$ mvn clean -Dtest=org.infinispan.query.distributed.DistributedMassIndexingTest test

Note: MassIndexer being implemented using the Map/Reduce algorithm, it requires to run within a cluster (ie several instances of ISPN).

If run within a single node cluster, the MassIndexer
