Can one of the admins verify this patch?

Context -
@sarangan12 - We are rebranding the concept/entity "Azure Search" to "Azure Cognitive Search" and we'd like that to be reflected in our SDK generated doc comments. This achieves that

@HeidiSteen - This is the logic we applied
In places where the term "Azure Search" is used as is (to reference a concept), we replace it with "Azure Cognitive Search".

In places where the term "Azure Search" is followed by a noun ("Azure Search service", "Azure search index", "Azure search indexer etc.,") we simply contract it to "search" + noun or remove "search" altogether as appropriate ("search service", "index", "indexer" etc.,)

@bleroy Your PR didn't pass validation. You should close and reopen the PR to see if the problem is transitory. I agree with all of Arvind's comments.

@HeidiSteen / @sarangan12 / @bleroy - the model validation failures are due to a "ENUM_MISMATCH" which is a known failure mode and we have obtained exceptions from the swagger folks.

@sarangan12 - @brjohnstmsft is on vacation, and I think my sign off is a reasonable substitute.
