Update of Hibernate 4 Search controlled FT index in response to the replication events (on MySQL)
Keep in mind that default indexer, which is used by FullTextIndexSynchronizer, relies on @org.hibernate.search.annotations.ContainedIn for propagation of indexing events to the container entity(ies). As a result, either each @IndexedEmbedded-annotated field/method MUST have corresponding @ContainedIn member (inside target entity) or a different indexer is required.
