I am new to ElasticSearch. I am working on a project where I have to search listings which matches the input `http://foo.bar/search?listing=123,456` . I have built an array which key and value are the same and representing the listing ids. I have tried to run the following example but it failed near contains. The script is built for painless language. However, I always get the runtime error.

I cannot get this to work, what could I be doing wrong?

```auto
 'function_score' => [
       'query' => $query,
           'score_mode' => 'sum',
              'functions' => [[
                'script_score' => [
                 'script' => [
                   'params' => ['listing' => [123 => 123, 456 => 456]],
    'source' => "(params.listing.contains(doc['id'].value) ? Math.pow(3, 3) : 0)",
                            ],
                        ],
                    ]],
                ],

```

If I understand the logic of your query, what you're trying to do is multiply the score by 27 if one of the IDs occurs in the `id` field. You can achieve that without a script, by using a [terms query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html) inside a filter function, instead of a script\_score function. I think this will be easier, as it will allow you to avoid having to do any scripting:

```auto
{
  "query": {
    "function_score": {
      "query": {
        YOUR_$QUERY
      },
      "functions": [
        {
          "filter": {
            "terms": {
              "id": [
                "123",
                "456"
              ]
            }
          },
          "weight": 27
        }
      ]
    }
  }
}

```

The thing is that I have to stick with scripting, as there are other scripts running

Alright. Why not simply pass in an array of values, rather than a map with key-value pairs? The following should work:

```auto
      "functions": [
        {
          "script_score": {
            "script": {
              "source": "(params.listing.contains(doc['id'].value) ? Math.pow(3, 3) : 0)",
              "params": {
                "listing": [
                  123,
                  456
                ]
              }
            }
          }
        }
      ]

```
