.net – How to show suggested content in response using Azure Cognitive Search?

I have created a new azure cognitive search in azure which has index related to articles. I want to implement in way that if users search for any article first response it should have suggested content, like in Google if we search for any keywords first it wil show some response with ads tag the same way I want to implement in azure cognitive search, and need some idea to implement Thanks in advance.

I have tried azure cognitive search suggester but its expecting exact or partial match for example, search keyword is ’always feeling tired” it will retrieve related articles which has keyword tired in it.

but what i expect:
if user search for keyword “always feeling tired” 1st response should be

1. Tiredness (one of article name this should be suggested first, note this article name doesn’t have keyword tired/feeling)
