if we support distributed stats (idf etc), then this assumption could break
down in a lot of cases, because the stats from the first phase don't make sense
with regards to the documents being scored in the second phrase.

They would make sense. Though it's like discussing the wind since RT isn't
completed. Sounds like you're thinking of a general retry? That's a good
idea, it would need to retry the entire distributed query in all phases.
That functionality should be modular and should not be 'pre-baked / canned'
into Solr. [Again] a simple policy class would suffice here.

> Leases/reservations on searcher instances would give us the ability to use

> send multiple requests and have them hit a consistent/unchanging view of the

> contacts the same replicas as before.
