How to make a search being executed on all nodes or a dedicate node?

I want a query being executed on each node, how to make it happened?

You cannot unless the data is distributed across all the nodes.

Thank Mark.

I have set the replica = node numbers -1, and find a way to do this:
GET /testindex/testype/_search?pretty=true&preference=_only_node:MSVzS6W4QNGI40pMjN9Axw

The node id can be get with the following request:
GET _nodes

Why are you even doing this though?

Hi Mark,

I leverage native script filter to implement a special filter logic, some caches are added internally to boost its performance, we need a way to invalidate some cache items basing on application side update, but the invalidation procedure needs to be applied on all ElasticSearch nodes to avoid inconsistency. Hope it explains.

Thanks,
Charlie
