No, the index is synced up automatically, as a result of the events -
passed inside the journal record - being delivered. In other words,
the search manager, responsible for updating the index, doesn't see a
difference between updates made by its own node and changes made by a
foreign node.

> 2) Are the other clusters updated immediately? For example, if one cluster adds a new node, is it immediately visible to other sessions in other clusters, as is mandated by the JCR spec?

Not actively. Other nodes in the cluster see the change inside a given
delay (5 seconds is the default) unless they itself try to perform
some changes, which causes an immediate sync.

Kind regards
