I currently have a 3 node cluster where each node has a complete copy of every index.

Based on the documentation on distributed search queries found here: [https://www.elastic.co/guide/en/elasticsearch/guide/current/\_query\_phase.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/_query_phase.html)

Do queries still go beyond the current node when searching if a node has all of the data it needs? If so, is there a way to configure things such that a query uses only the current node?

You can control this by using [preference](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/search-request-preference.html), especially the `_local` one.

If, as he says, the index is fully replicated on every node in the cluster, won't ES automatically prefer the `_local` one?
