> I imagine this approach is doing query work in parallel without any extra code? Yes, that's my understanding too. > I see no accommodations for faceting to ensure we don't wastefully compute the docSet. Yeah, my understanding is that with this sort of approach there is conceptually no (obvious) support for faceting. Today, Solr's client would make two queries and then outside-of-Solr do the RRF locally -- conceptually that is what the approach here does too. Because the query work is in parallel and the doc sets are (I think) not passed back to where the fusion happens, then truly-correct faceting would not implicitly be available. ... ... having said that, currently the sub-queries are there and there are only sub-queries, so I imagine a fusion-aware faceting component might do an OR of the sub-queries and then send that for faceting purposes only i.e. with `rows=0` to the shards. -- This is an automated message from the Apache Git Service.
