I guess you could do it mostly transparently for the user. Set a reasonably high timeout like say 2 mins, then every n operation look how much you've consumed. If you are close to the limit, you commit and restart a transaction. So your option would be semi public. hibernate.search.massindexer.transaction_timeout auto|time in (m)s
If a user is in trouble with the auto system, we give him the option.
