Prioritize search results based on certain parameter in AzureSearch.

I have an index on AzureSearch similar to this one:

"fields": [
    {
        "name": "key",
        "type": "Edm.String",
        "filterable": true,
    },
    {
        "name": "title",
        "type": "Edm.String",
        "searchable": true
    },
    {
        "name": "followers",
        "type": "Collection(Edm.String)",
        "filterable": true,
    }
]

Here, title is the title of a Post and its text searchable. followers contains the user ids of users who are following that particular Post.

I am getting current logged in userId from session. Now when a user does some text search, I want to show those Posts on top which current user is following.

Please tell if this is achievable in AzureSearch using ScoringProfiles or anything else?

Tag boosting in ScoringProfile does exactly that. All you need to do is to add a scoring profile as below : 

{
  "scoringProfiles": [
  {
    "name": "personalized",
    "functions": [
    {
      "type": "tag",
      "boost": 2,
      "fieldName": "followers",
      "tag": { "tagsParameter": "follower" }
    }
    ]
  }
  ]
}

Then, at query time, issue a search query with the scoring profile with the parameters to customize the ranking :

docs?search=some%20post&&scoringProfile=personalized&scoringParameter=follower:user_abc

Hope this helps. You can read more about it here. https://azure.microsoft.com/en-us/blog/personalizing-search-results-announcing-tag-boosting-in-azure-search/
