Hello,

is it possible to index only some entities? The filtering that I need to make is based on non-indexed fields in a referenced entity.

I tried implementing my own hibernate.search.worker.backend, but the queue received there consists of values already translated to Lucene, without access to the original entity.

Is there any other way?

Hi,

It's going to index only the entities marked with @Indexed


Make them indexed?
Did you see @IndexedEmbedded and @ContainedIn in the docs?

Sorry for the simplistic answer, I sincerely hope to have you given some ideas but I realize that most probably I didn't understand what your question is.

Hello,

I have the entity marked with @Indexed, but what I wanted to achieve is to index only some instances, that is, only some rows in the table, basing on the value of some field.

Ideally, I'd like a filter deciding which instances of an entity are indexed, and which aren't.

thanks, now I understand.

It is currently not possible to completely skip the index-insertion on a per-instance logic, still a good workaround is to add an additional boolean field (e.g. Field(include:false), so you can filter on it when doing searches.

You may add a custom @ClassBridge, or you could add a method returning boolean marked with both @Transient and @Field;

So there's much flexibility in how you index and you could implement this behavior, only needing an additional field; The bad news is that your index will contain some unneeded data, the good news is that when you'll change your mind and will need the objects you left out it will be possible to search on them.

You may ask for it as a new feature but I'm not sure the maintainers will accept it: you'll have to convince them.

I see ... well, maybe @ClassBridge + an additional field is a good way out. Thanks for the help :)
