Force search on a local node?

Hi -

I am new to Elasticsearch and have what I hope is a basic question for a
simple configuration. Assume I have 3 node cluster with a single index and:

  • 1 primary shard
  • 2 replicas of the primary shard

The majority of requests will be searches with relatively few index updates.

All requests are distributed by a network load balancer across the three
nodes. Since each node has a copy of the index and the requests are being
spread across the cluster by the network load balancer, my intuition is
that a local search (i.e. execute a search on the node that received the
request) will perform best. In other words, I do not want Elasticsearch to
round-robin each search request from the node received to another node; I
want the node that received the request to search its local copy of the
index.

My question: Is there a way for make Elasticsearch search against only the
shard on the node received (and avoid a network hop to another shard)?

Thanks very much.
