Using multiple JGroups based indexes causes multiple values in the index
------------------------------------------------------------------------

                 Key: HSEARCH-1089
                 URL: https://hibernate.onjira.com/browse/HSEARCH-1089
             Project: Hibernate Search
          Issue Type: Bug
    Affects Versions: 4.0.0.Final
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
            Priority: Critical
             Fix For: 4.1.0.Final, 4.1.0.CR3


When having more than one JGroups channel listening for updates, each different master will forward the received work to the appropriate IndexManager.
So having for example 4 indexes configured to use JGroups, each of the 4 masters will receive the work and forward it, so (unless it's an idempotent operation such ad delete) you' ll get 4 copies of an added Document.

Workaround: isolate channel names or ports of each different JGroups backend.
