如何使用Elasticsearch来；随机化；PHP中的搜索结果？

我试图使用Elasticsearch的功能评分，但也邀请了其他方法

我现有的搜索结果如下所示：

$searchParams['body']['query']['filtered']['query']["match_all"] = array("boost" => 1);

如何将函数\ U分数添加到此搜索？这是我现在拥有的

$randomScore = new \stdClass();
// will be date or userid in the future
$randomScore->seed = 5; 
$functionScore = array(
            array("random_score" => $randomScore)
        );
$searchParams['body']['query']['function_score']['functions'] = $functionScore;
$queryResponse = $client->search($searchParams);

这似乎非常接近正确。我只是需要更多的脑力。

你需要做两件事：

将查询嵌套在“函数\分数”数组中

这些函数需要嵌套在一个额外的数组[]中

以下内容适用于我，请根据您的需要进行相应更改：

    $params = array();

    $params['body']['size'] = 10;
    $params['body']['from'] = 0;

    $random = new \stdClass();
    $random->seed = time(); //change this to make randomization consistent, e.g. user id
    $params['body']['query']['function_score']['functions'][]['random_score'] = $random;
    $params['body']['query']['function_score']['query']['bool']['must_not'] = array(
        'term' => array(
            '_id' => $this->get('currentPageId'),
         )
    );
    $params['body']['query']['function_score']['query']['bool']['must'] = array(
        'term' => array(
            'isAlias' => false
         )
    );
