We have index mapping like this:

{
   "mappings": {
      "_source": {
         "includes": [
            "uid"
         ]
      },
      "properties": {
         "follow": {
            "doc_values": true,
            "eager_global_ordinals": true,
            "index_options": "docs",
            "type": "keyword"
         },
         "staticRank": {
            "index": false,
            "type": "long"
         },
         "id": {
            "doc_values": false,
            "norms": false,
            "type": "keyword"
         }
      }
   },
   "settings": {
      "index": {
         "knn": false,
         "merge": {
            "policy": {
               "segments_per_tier": 2
            }
         },
         "number_of_replicas": 0,
         "number_of_shards": "3",
         "refresh_interval": "-1",
         "sort": {
            "field": "staticRank",
            "order": "desc"
         },
         "store": {
            "type": "mmapfs"
         }
      }
   }
}

where "follow" is users which the candidate 'id' is connected to. When we make a search query, we do match on the "follow" terms and that way we retrieve candidates which are 2-levels away from the searcher.

Our query is like this:

{
   "query": {
     "terms": {
       "follow": [ "id5", "id99", "id9" ],
       }
   }
 }

This gives me any candidates where scores are all 1.

How can i run a query so that i get results where the scores are sorted in descending order and score signifies the overlap b/w searcher's "follow" and candidate's "follow" fields?
