Marc Schipperheyn commented on HSEARCH-499:
-------------------------------------------

I was thinking about this yesterday and what if in stead of a soft delete filter, you have a soft delete @DocumentFieldBridge at the field level? Each bridge would determine if a document gets removed, updated, deleted, based on the value of the field, just like the filter does now. This way the MassIndexer could more easily access this information. Downside would be a potential (slight?) performance loss with multiple bridges like this in case of multi field evaluations.

> I was discussion the MassIndexer API. It would be nice to be able to filter the list of Entity ids to reindex based on a query:
> For example
> select u.id from User u where u.lastUpdate >= :yesterday
> or sue some kind of other flag.
> This would be a nice useful trick.
