我在PHP中有一个查询，它已经在工作了，现在我想用function_score扩展它。目标是我可以基于时间戳来提升更新的内容。
我发现了这篇文章https://discuss.elastic.co/t/how-to-prioritize-more-recent-content/134100，也在阅读这篇文档https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html。
我想这是一种错位的新的一部分，但我不知道把它放在哪里。我很新的ElasticSearch。

错误

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

新零件

'function_score' => [
    'functions' => [
        [
            'filter'=> [
                'range' => [
                    'tstamp' => [
                        'gte' => 'now-1y',
                        'lte'  => 'now'
                    ]
                ]
            ],
            'weight' => 5
        ],
        [
            'filter' => [
                'range' => [
                    'tstamp' => [
                        'gte' => 'now-3yr',
                        'lte' => 'now-1yr'
                    ]
                ]
            ],
            'weight' => 2
        ]
    ],
    'boost_mode' => 'multiply'
