Could you verify that using an `EntityIndexingInterceptor` as an alternative actually works for this purpose?
We'd need to add a test to guarantee that such an interceptor wouldn't also block the behaviour for an invocation of

org.hibernate.search.FullTextSession.index(T)

.

What about the MassIndexer ? I think it should be able to reindex entities which are set to "manual" too, but I wonder if that's the general sentiment.
