            2,
            3,
            4
          ]
        }
      }
    ]
  }
}

As you can see, [1, 2, 3] has same score as [1, 2, 3, 4] where there were two matches [3, 4].

Is it possible to score the documents more based on no. of values matched ?

I want [1, 2, 3, 4] to score higher.

Hi @Divit_Sharma

Try add match inside should clasule.

 {
          "match": {
            "items": "3"
          }
        },
        {
          "match": {
            "items": "4"
          }
        }

Two items to search was just an example.

Array to be searched can be of any no. of values. This example would make me use multiple match blocks based on the no. of values in array. So not what I am looking for.

Another solution was to use:

{ "match": { "items": "3 4" }

But this fails for long values.

Okay this seems to work but I can't just pass the list will have to build the search string as value1 OR value2 OR value3 etc.

      "should": [
        {

            "query": "items: (3 OR 4)"
          }
        }
      ]
    }
  }
