    Starting in MongoDB 4.2, MongoDB adds the parameter
-   :parameter:`ShardingTaskExecutorPoolReplicaSetMatching` that
-   determines the minimum size (can vary during runtime) of the
-   :binary:`~bin.mongos` instance's connection pools to each member of
-   the sharded cluster.
-
-   By default, for each replica set in the sharded cluster (i.e. shard
-   replica set and config servers), :binary:`~bin.mongos` maintains
-   connection pools to each replica set secondary that are at least
-   equal to the size of its connection pool to the primary.
+   :parameter:`ShardingTaskExecutorPoolReplicaSetMatching`. This 
+   parameter determines the minimum size of the 
+   :binary:`~bin.mongod`/:binary:`~bin.mongos` instance's 
+   connection pool to each member of the sharded cluster. This value 
+   can vary during runtime.
+   
+   :binary:`~bin.mongod` and :binary:`~bin.mongos` maintain connection
+   pools to each replica set secondary for every replica set in the 
+   sharded cluster. By default, these pools have a number of connections
+   that is at least the number of connections to the primary.  
 
    To modify, see :parameter:`ShardingTaskExecutorPoolReplicaSetMatching`.
