我需要構建查詢來獲取 doc.value1 == doc.value2 的文檔{    "query": {        "bool" : {            "filter" : [{                "script" : {                    "script" : {                        "source": "doc['val1'].value == doc['val2'].value",                        "lang": "painless"                     }                }            }]        }    }}這是我需要用 olivere/elastic 構建的，如果我將其作為 POST 請求發送，它就可以工作。在 golang 我有類似的東西"github.com/olivere/elastic"...query := elastic.NewBoolQuery()// then add something to this query or leave it empty it works fine// but if I add query = query.Filter(elastic.NewBoolQuery().Must(elastic.NewScript("doc.['val1'].value == doc.['val2'].value")))// I'm getting: Error 400 (Bad Request): [source] query malformed,// no start_object after query name [type=parsing_exception]// Then i run it like:client, err := elastic.NewClient()if err != nil {    fmt.Println(err)    return}resp, err := client.Search("myIndex").Type("myDoc").Query(query).TrackTotalHits(true).Size(limit).Do(context.Background())    if err != nil {        fmt.Println(err)        return    }
