elasticsearch aggs和查询大小

Question

我使用elasticsearch，但我对aggs有一点问题，因为我为我的查询设置了一个大小，如

$params ['body'] ['size'] = 1;

我使用像

这样的aggs

$params ['body'] ['aggs'] ['grouped_by_name'] = array (
            "terms" => array (
                    "field" => "title",
                    "size" => 0 
            ) 
    );

但是在我的doc_count中，我收到的不仅仅是为什么？

我只能接收我需要的aggs

$params ['body'] ['size'] = 1;  <------ this is how much hits you want, 0 mean 0

$params ['body'] ['aggs'] ['grouped_by_name'] = array (
        "terms" => array (
                "field" => "title",
                "size" => 1 <-------------- this size is how much of this aggs you want, 0 mean infinity 
        ) 
);
