Answer 1

custom_score在新版本中已弃用。使用功能分数查询而不是custom_score。

custom_score查询

"custom_score": {
"params": {
    "param1": 2,
    "param2": 3.1
},
"query": {...},
"script": "_score * doc['my_numeric_field'].value / pow(param1, param2)"
}

变成

"function_score": {
"boost_mode": "replace",
"query": {...},
"script_score": {
    "params": {
        "param1": 2,
        "param2": 3.1
    },
    "script": "_score * doc['my_numeric_field'].value / pow(param1, param2)"
}
}
