Error on response after modifying request API from _msearch to _search
Affected Projects: Reactivesearch / ReactiveCore
Library Version: 3.0.1
Describe the bug
Using the Reactivesearch documentation as a baseline, I changed the request API endpoint as follow:
The request was processed nicely by Elasticsearch. However, the following error was thrown while the library was processing the response:
As I checked, the problem is that the handleResponse method tries to directly access a "responses" property from the body, and the search API doesn't return an array of responses - it returns a single response.

To Reproduce Steps to reproduce the behavior: Just modify any request using transformRequest as described above.
Expected behavior The single response from the _search API should be processed succesfully.
