function_score query doesn't have filter property

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html

The "filter" property isn't available.

Sample query:

curl "http://localhost:9200/test_score/test_type/_search?pretty" -d '{
    "query": {
        "function_score": {
            "filter": {
                "query": {
                    "multi_match": {
                        "query": "John Wayne",
                        "fields": ["title", "credits"]
                    }
                }
            },
            "functions": [
                {
                    "filter": {
                        "query": {
                            "match": {"title": "John Wayne"}
                        }
                    },
                    "weight": 1
                },
                {
                    "filter": {
                        "query": {
                            "match": {"credits": "John Wayne"}
                        }
                    },
                    "weight": 1
                }
            ],
            "score_mode": "sum"
        }
    }
}'

@gmarz / @Mpdreamz Maybe we do have a way to do this? Thanks :)

@GlenRSmith thanks for reporting this.

@gmoskovicz Looks like it's simply missing. It's just a matter of adding IFilterContainer to IFunctionScoreQuery and all the supporting code that goes with it. Just like IQueryContainer.
