                }
            }
        }
    }
}

This is the test data：

{"index":{"_id":"cust0","routing":"cust0"}}
{"cust_no":"1008263","age_numvalu":10,"name":"cust0","f3v":912.0,"id":"10000","f1":"1","f2":"g","f3":"l","relation":{"name":"label"}}
{"index":{"_index":"cust_label_father_son_model","routing":"cust0"}}
{"buy_amont":"2440","cust_no":"1008263","total_amont":"10364","relation":{"name":"custProduct","parent":"cust0"}}
{"index":{"_index":"cust_label_father_son_model","routing":"cust0"}}
{"buy_amont":"8318","cust_no":"1008263","total_amont":"8705","relation":{"name":"custProduct","parent":"cust0"}}
{"index":{"_index":"cust_label_father_son_model","routing":"cust0"}}
{"buy_amont":"6651","cust_no":"1008263","total_amont":"13456","relation":{"name":"custProduct","parent":"cust0"}}
{"index":{"_index":"cust_label_father_son_model","routing":"cust0"}}
{"buy_amont":"5036","cust_no":"1008263","total_amont":"96117","relation":{"name":"custProduct","parent":"cust0"}}
{"index":{"_index":"cust_label_father_son_model","routing":"cust0"}}
{"buy_amont":"6151","cust_no":"1008263","total_amont":"72155","relation":{"name":"custProduct","parent":"cust0"}}
{"index":{"_index":"cust_label_father_son_model","routing":"cust0"}}
{"open_account_amont":"490362","cust_no":"1008263","open_account_date":"2021-03-02","relation":{"name":"custDeposit","parent":"cust0"}}

I can't get the data by using the following methods：
http://127.0.0.1:9200/cust_label_father_son_model/_search

{
    "query": {
        "has_child": {
            "type": "custProduct",
            "query": {
                "bool": {
                    "filter": [
                        {
                            "range": {
                                "buy_amont": {
                                    "gte": 80
                                }
                            }
                        },
                        {
                            "match": {
                                "total_amont": 10364
                            }
                        }
                    ]
                }
            }
        }
    }
}

But I can get the data in the following way, why
http://127.0.0.1:9200/cust_label_father_son_model/_search

{
    "query": {
        "has_child": {
            "type": "custProduct",
            "query": {
                "bool": {
                    "filter": [
                        {
                            "range": {
                                "buy_amont": {
                                    "gte": 100
                                }
                            }
                        },
                        {
                            "match": {
                                "total_amont": 10364
                            }
                        }
                    ]
                }
            }
        }
    }
}

Why do you get no data over 80, but you can get data over 100
