Does MarkLogic replicas forests will also take participate in search queries

We have configured MarkLogic as follows

Host 1:    master_forest_01     replica_forest_03
Host 2:    master_forest_02     replica_forest_01
Host 3:    master_forest_03     replica_forest_02

Everything is working fine.

Master forests are in "open" state and replicas are in "sync replicating" state

As far as i know, only forests with open state will participate in search queries, and with "sync replicating" will wait for failover scneario

I want to confirm if this assumption is right or not. Or it takes participation to improve performance?

Can we just add Host4 with only replicas forest, will this boost performance? I mean we want to know, what more to do to improve performance?

Replica forests (setup for HA) will not participate in search. They are available to seamlessly handle fail-over.

If you think adding another forest will improve performance, you should do that as a master forest with a replica setup).

Having said that, measure against your SLA in a perf environment before you think you need more forests. Simply adding forests (for parallelization) without measuring against your SLAs may not help you.
