_score字段没有经过计算,因为它没有用作排序。date 首先,在每个结果中增加了一个 sort 在这个例子当中 date字段在内部被转为毫秒,即长整型数字1411516800000等同于日期字符串 2014-09-24 00:00:00 UTC。 其次就是 _score 和 max_score 字段都为 null。 计算_score 是比较消耗性能的, 而且通常主要用作排序 -...
es _score null 没有筛选 es value_count,1、度量聚合度量聚合从文档中提取值并进行计算,这些值通常从文档中的字段中提取出来,也可以使用脚本进行计算。数字型度量聚合是一种特殊类型的度量聚合,输出数字类型的值,聚合输出一个数字指标的为单值数字型度量聚合;输出多
在上面的例子中,coordinating node 拿到(from + size) * 6条数据,然后合并并排序后选择前面的from + size条数据存到优先级队列,以便 fetch 阶段使用。 另外,各个分片返回给 coordinating node 的数据用于选出前from + size条数据,所以,只需要返回唯一标记 doc 的_id以及用于排序的_score即可,这样也可以保证返回...
