}

错误是：

[function_score] malformed query, expected [END_OBJECT] but found [FIELD_NAME]

布尔查询本身可以完美运行，但是一旦我使用 function_score，它就会停止工作。我试图遵循这个例子：https://www.elastic.co/guide/en/elasticsearch/guide/master/boosting-by-popularity.html

任何关于我做错了什么的想法将不胜感激！

您必须将field_value_factor 放在更高一级，在function_score 内：

    "query": {
        "function_score": {

                            }
                        }
                    ]
                }
