> Hi,
> I know it's not exactly documented but, before 3.4, it was possible to index a collection with the @Field annotation and a FieldBridge (in our case, a FieldBridge which indexes all the ids of the linked entities).
> We use it a lot instead of @IndexedEmbedded because it allows us not to bloat our index when we want to index a collection containing indexed entities (@IndexedEmbedded integrates all the fields of the linked entities in the index of the main entity - which is often not needed in our case: we have autocomplete field for our search so we only need the id of the linked entities).
> Starting with 3.4, it doesn't work anymore: the entity is correctly indexed when created but, if we update only the collection, the index is not updated.
> The problem is in AbstractDocumentBuilder.isCollectionRoleExcluded(String collectionRole) which is called to check if the collection update should trigger a reindex. This method should also consider the collections having a @Field annotation, not just the collections with @IndexedEmbedded or @ContainedIn.
> FWIW, if somebody else has this problem, as a workaround, I use a non default boost strategy to force the reindex but it would be nice to have it fixed because it's really a useful pattern.
> If needed, we can provide a test case.
> Thanks.
