FOSElasticaBundle CustomScore查询分页 [英] FOSElasticaBundle CustomScore query pagination

问题描述

我刚刚开始使用FOSElasticaBundle，到目前为止，发现它真的很好用。我不知道我是否对于Elastica或者Elastica的缺乏知识，或者我对于ElasticSearch的知识缺乏一般性，但是是否可以使用分页式的CustomScore查询？

I have just started using the FOSElasticaBundle and have so far found it really good to use. I am not sure if it is my ignorance of the bundle/Elastica or my lack of knowledge about ElasticSearch in general, but is it possible to have a CustomScore query with pagination?

如果我尝试在CustomQuery对象上调用setFrom / setSize，我被告知该方法不存在。如果我创建一个Query对象并将其设置为size，并将此查询传递给CustomScore查询对象，那么分页参数将被忽略。我已经包含了我的代码副本，这是值得的...

If I try calling setFrom/setSize on the CustomQuery object I am told that the methods do not exist. If I create a Query object and setFrom and size there and pass this query into the CustomScore query object then the pagination parameters are ignored. I have included a copy of my code for what it is worth...

        $queryString = new QueryString();
        $queryString->setFields(array('_all'))
            ->setDefaultOperator('OR')
            ->setQuery($terms);

        $query = new \Elastica\Query();
        $query->setQuery($queryString);
        $query->setSize($maxItems);
        $query->setFrom(($page - 1) * $maxItems);

        $custScoreQuery = new CustomScore();
        $custScoreQuery->setQuery($query);
        $custScoreQuery->setScript("_score * (doc['section.id'] == 7) ? 0.5 : 1");
        $index   = $this->get('fos_elastica.index.search_en_gb');
        $results = $index->search($custScoreQuery);

任何帮助都乐意接受：o）

推荐答案

Size和From必须应用于顶级查询，您将在这里丢失。

Size and From must be applied to the top level query, you are losing them here.

尝试这样：

$queryString = new QueryString();
$queryString->setFields(array('_all'))
        ->setDefaultOperator('OR')
        ->setQuery($terms);

$custScoreQuery = new CustomScore();
$custScoreQuery->setQuery($queryString);
$custScoreQuery->setScript("_score * (doc['section.id'] == 7) ? 0.5 : 1");

$query = new \Elastica\Query();
$query->setQuery($custScoreQuery);
$query->setSize($maxItems);
$query->setFrom(($page - 1) * $maxItems);

$index   = $this->get('fos_elastica.index.search_en_gb');
$results = $index->search($query);

此外，打开Elastica中的日志，您将可以看到是否有大小和偏移量。话虽如此，当然分页与定制分数一致。

Also, turn on the logs in Elastica, and you will be able to see if there is a "size" and "offset" in the Json query. That being said, of course pagination works with custom score.
