Attributes to be set in distsearch.conf

[username021]

I read that the distsearch.conf is to configure only distributed search.
In order to set the distributed search , I have set the distsearch.conf ENABLED in my Splunkweb(Search head).
It creates the file in the Search head --> (distsearch.conf)

In my deployment , I have

deployment server-1

heavy forwarder-1

Indexers -2

Do i need to add all the Splunk instance(incl. forwarder,deployment server) in 'servers' attribute ? or only the search head IPs ?

distsearch.conf

 #This file contains possible attributes and values you can use to configure distributed search.
[distributedSearch]
servers = 10.x.x.x:8089,10.x.x.x:8089

In distsearch.conf

in Servers you need to add only search-peers(Indexers or where data is being stored)
