I remember once seeing something that related to es query exeuction not sure if its for get and also a search but for every shard in the index it has to query each of them until it finds the shard that has the dataset and it does not do all the shards at once but one at a time. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I think you confuse something. for a `get` action ES only ask one shard since it knows where to go. For a `search` it queries all shards (one replica of each shard) and merges the results but that happens in parallel. simon On Sunday, March 3, 2013 8:52:27 AM UTC+1, Wojons Tech wrote: > I remember once seeing something that related to es query exeuction not > sure if its for get and also a search but for every shard in the index it > has to query each of them until it finds the shard that has the dataset and > it does not do all the shards at once but one at a time. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
