One my biggest problems with HSearch has always been saving an item and because of IndexedEmbedded getting a cascade of queries to reindex the entire object graph. This can be mitigated by caching but is best avoided all together.
It allows you a kind of inner join between indexes and is quite performant.
I'm already using this to great effect. The feature has I think matured in Lucene 4.x, although there is still some work left, and I'm wondering if this would be a valuable addition to the DSL api.

One interesting way to avoid this is using the QueryTimeJoin feature
