Description
Introduce allocation filter to control placement of search only replicas.
The new filter
cluster.routing.allocation.search.replica.dedicated.includeacts as a normal include filter in that you can specify multiple values and search shards will allocate there if one of the attributes is present on a particular node. However, it is different from existing include filters in that it is exclusive to search replicas and will exclude any non search shard for all of the attributes set.Related Issues
