Context

The Go Driver does not make it clear that creating / updating / dropping search indexes is asynchronous. Per the specifications:

The search index commands are asynchronous and return from the server before the index is successfully updated, created or dropped. In order to determine when an index has been created / updated, users are expected to run the listSearchIndexes repeatedly until index changes appear.

Definition of done

Include the above form the specifications in the comments concerning index CRUD operations.
