hola, 1) When distributing search across several Shards, is the merged result reflects the overall ranking, cross-shards? I'm talking about stuff like "document frequency". I guess it does, otherwise distributed search wouldn't have overhead.
talking about overhead, 2) is there a known ratio of the overhead of using shards against single core, and the impact on performance for adding the N+1 shard to the distributed index? thanks for any knowledge/thought. ShlomiJ
