Check value exists in params array using ElasticSearch painless script

Question

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?

 '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)",
                            ],
                        ],
                    ]],
                ],

You can make use of the below query. You can check the script part as how what you need has been implemented.

POST <your_index_name>/_search
{
  "query": {
    "function_score": {
      "score_mode": "sum", 
      "query": {
        "match_all": {}
      },
      "functions": [
        {
          "script_score": {
            "script": {
              "source": """
                  boolean allValues = false;
                  for(int i=0; i<params.value.size(); i++){
                    if(doc['id'].value.contains(params.value.get(i))){
                      allValues = true;
                    }else{
                      allValues = false;
                      break;
                    }
                  } 
                  if(allValues){
                    return Math.pow(3,3)
                  } else {
                    return 0;
                  }
                """,
              "params":{
                "value": ["123","456"]
              }
            }
          }
        }
      ]
    }
  }
}

What the query does is, it checks to see if all the values present in params i.e 123 & 456 is present in the id field, if it does, it would go ahead and calculate score accordingly.

Not that id field is a keyword when I tested the query at my end.

You can use the query accordingly in your php script. Let me know if this helps!

Didn't work, gives me compile error. Whats inside contain in my case is a collection and not an object. – Beerbohm

@Beerbohm I know about that and looking at your script using a collection doesn't make sense if all you want is to verify if url contains a set of values. Wouldn't array be better off with it? And also did you try to run the above query from Kibana or Postman? I want to make sure that the above query runs in your machine using one of rest client tools. Also you can change from source to inline and give it a try if you end up with any compilation error mentioning about source – Freely

it did not work, is there a way to stick with what I put using source – Beerbohm
