Server Group Awareness lacking detail on Index Service

The documentation for Server Group Awareness states the following:

Server Group Awareness only applies to the Data Service.

This should be updated to reflect the fact that Server Group Awareness also applies to the Index service. Indexes and index replicas are distributed to nodes in separate server groups where possible to ensure the index remains available if one group goes down, just as with the Data Service and vBuckets.

There is little mention on this page of how the Index Service makes use of Server Group Awareness. This could be improved by including a section which has a more comprehensive explanation of the distribution of indexes and index replicas to different server groups where possible. Perhaps the opening paragraph could also be updated to mention this briefly, as currently, the only mention of the Index Service in relation to Server Group Awareness is far down the page under the Group Failover and Service Availability heading.
