Documentation related to index node recovery is incorrect

The documentation on the below page related to Index Service recovery is incorrect:

https://developer.couchbase.com/documentation/server/5.5/clustersetup/rejoin-cluster.html
https://developer.couchbase.com/documentation/server/5.1/clustersetup/rejoin-cluster.html

1. Full Recovery

"Indexes must be rebuilt on the server node that is being re-added."

The indexes don't need to be rebuilt after recovery. If this line pertains to View Indexes, then it needs to be clarified.

2. Delta Node Recovery

" Index nodes retain their index definitions when being failed over and recovered using delta recovery, although the data within the indexes is deleted. When they are re-added to the cluster, the indexes will be automatically rebuilt by the Index service. "

The index data is not deleted. It is rather preserved and when the recovered node gets re-added, it continues from the point where it left off.

3. Similar to 2 is repeated under section "Delta recovery characteristics"

"Index definitions are retained on the node being recovered. Once the node has been re-added, these indexes are automatically rebuilt by the Index service."

This also needs to be corrected.

4. With different services supporting indexes (e.g View/GSI/FTS Indexes), it would be better break up this page into sub-sections describing the behavior of each service. It is not clear which "Index" the documentation refers to.
