Sanne Grinovero commented on HSEARCH-499:
-----------------------------------------

definitely agree, actually in my previous experiments I had this as I needed it, but it's implementation was coupled to my model.

I believe we chatted about the possibility to use a DetachedCriteria, but you where not 100% convinced about it. Should try by HQL?

oh and the API should be able to pass something like a Map<rootTypeClass,filter> as each root type would have it's own fetching filter.

The same filtering would need a way to define efficient purging on the same dataset, or we need to switch to (delete+write)* for each id rather than having purgeAll+(add)*

> 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.
