elasticsearch 7，按整数值boost

Question

我试图通过“created”字段（整数/时间戳）增强搜索，但总是遇到

"{"error":{"root_cause":[{"type":"parsing_exception","reason":"Unknown key for a START_OBJECT in [script].","line":1,"col":181}],"type":"parsing_exception","reason":"Unknown key for a START_OBJECT in [script].","line":1,"col":181},"status":400}"

如果没有“脚本”，查询工作正常。但是我没有什么想法如何正确地写这个脚本。有什么想法吗？

 return [
            'index' => 'articles_' . $this->system,
            'body'  => [
                'size' => $this->size,
                'from' => $this->start,

                'sort'  => [
                    $this->order => 'desc',
                ],
                'query' => [
                    'query_string' => [
                        'query'            => $this->term,
                        'fields'           => ['title^5', 'caption^3', 'teaser^2', 'content'],
                        'analyze_wildcard' => true,
                    ],
                    'script' => [
                        'script' => [
                            'lang' => 'painless',
                            'source' => "doc['@created'].value / 100000",
                        ],
                    ],
                ],
            ],

        ];

编辑：更新了查询，但仍然遇到“{”错误“：{”root_case“：[{”type“：”parsing_exception“，”reason“：”[query_string]格式错误的查询，预期[END_OBJECT]但找到[FIELD_NAME]“，”line“：1,”col“：171}，”status“：400}

脚本不是一个独立的属性。它应该是布尔的一部分。当您有多个筛选器时，这些筛选器应该位于bool下的must/shoul/filter中

'body'  => [
                'size' => $this->size,
                'from' => $this->start,

                'sort'  => [
                    $this->order => 'desc'
                ],
                'query' => [
                      'bool' => [
                          'must' =>[
                              'query_string' => [
                                'query'    => $this->term,
                                'fields'   => ['title^5', 'caption^3',                        'teaser^2', 'content'],
                                'analyze_wildcard' => true
                              ],
                             'script' => [
                                'script' => [
                                  'lang' => 'painless',
                                  'source' => "doc['@created'].value / 100000"
                                ]
                              ]
                          ]
                      ]
                ]
            ]

上面会有括号的语法问题（我测试不出来），查询结构是正确的
