[Sanne Grinovero (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-1006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=44605#comment-44605 ] 

Sanne Grinovero commented on HSEARCH-1006:
------------------------------------------

I don't really see how we can guarantee consistency between database and index by just taking an index snapshot, as some work might be "in the pipeline" and not applied yet.
We can do this, but the only safe solution is to rebuild the index via the MassIndexer.. unless we allow to lock/freeze all transactions and flush the backends.
