Elasticsearch - [function_score] 格式错误的查询，应为 [END_OBJECT] 但找到 [FIELD_NAME]答案

【问题标题】：Elasticsearch - [function_score] malformed query, expected [END_OBJECT] but found [FIELD_NAME]Elasticsearch - [function_score] 格式错误的查询，应为 [END_OBJECT] 但找到 [FIELD_NAME]
【发布时间】：2022-10-25 12:51:52
【问题描述】：

我在 PHP 中有一个已经在运行的查询，现在我想用 function_score 扩展它。目标是我可以根据时间戳提升更新的内容。

我找到了这篇文章https://discuss.elastic.co/t/how-to-prioritize-more-recent-content/134100，并且还在阅读这篇文档https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html。

我想这是新零件的某种错位，但我不知道该放在哪里。我对 Elasticsearch 很陌生。

错误

        "type":"parsing_exception",
        "reason":"[function_score] malformed query, expected [END_OBJECT] but found [FIELD_NAME]"

新的部分

                         'function_score' => [
                            'functions' => [
