-----------------------------------------

Hi Zach,
good catch! This shouldn't be an issue anymore in Search versions >4.0 as uniqueness is now controlled by the index name, but apparently no tests are covering this scenario.
Would you like to contribute a testcase? We should include (test+fix) in 3.4.x and (test) in 4.x, assuming 4.x doesn't break too.

> InfinispanDirectoryProvider doesn't implement hashCode/equals.  When multiple subclasses of the same type share the same index directory duplicates are created.  The end result from an application perspective leads to duplicate search results, and lots of side effects like:
> java.io.FileNotFoundException: Error loading medatada for index file: _b.fnm|M|Location
> at org.infinispan.lucene.InfinispanDirectory.openInput(InfinispanDirectory.java:300)
> The errors and duplicates go away after overriding hashCode/equals based on directoryProviderName
