-----------------------------------------

Hi Adam,
thanks for the report. I guess only B is @Indexed right?
About use case #1, changing the value of the Collection<B> will require a re-indexing of each B instance which was in the collection before, or after. Remember an index is not update-able, so we have to rebuilt the index line for each B instance from scratch.
Use case #2 should NOT trigger indexing however, unless A is being annotated with _ at DynamicBoost_ or _ at ClassBridge_; if that's not the case, could you please provide a test case? I'll be glad to look into it. To create one, please have a look at what Tom and me created for this issue: _org.hibernate.search.test.engine.optimizations.CollectionUpdateEventTest_, it would be nice to patch that to cover your case as well.

> This problem seems related to HSEARCH-361.  An entity that references another entity as @ContainedIn is causing the load of entities related to the other entity.  
> Using the model below, the update of the collection of D instances in the class C causes the load of related classes B and A.
> {code}
> public class A {
>    @Field
>    private String name;
>    @IndexEmbedded
>    private B
> }
> {code}
> {code}
> public class B {
>    @ContainedIn
>    private A a;
>    @IndexEmbedded
>    private C c;
> }
> {code}
> {code}
> public class C {
>    @ContainedIn
>    private Collection<B> b;
>    // NOT INDEXED
>    private Collection<D> d;
> }
> {code}
> {code}
> public class D {
>    public String value;
> }
> {code}
