1）我有一个索引＆＃34;数据＆＃34;其中有479427个文件。为了获得我使用GET /data/_search的计数，我得到了这样的响应
"hits": {
"total": 479427,
"max_score": 1,
2）我使用count api GET /data/_count进行了检查，我得到的回答是这样的
{
"count": 479427,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
}
}
FROM 1和2文章数相同。
但是当我尝试GET /data/_stats命令时，我在get和total字段中获得了不同的计数。

我甚至在策展人中通过给予curator_cli show_indices --verbose给出了同样的答案：
data open 11.1GB 4814308 5 1 2017-05-31T13:00:37Z
为什么会有差异？
更新----------------------
1）您的意思是统计API会将嵌套的每个字段视为文档吗？
注意：BTW I am talking about the total.docs.count field in stats api。
2）计数API将根据唯一ID给出索引中存在的文档计数。
所以我的问题是，如果我想知道索引中有多少文档，api给出了正确的数量count，get，stats或curator_cli show_indices --verbose （使用策展人）？
由于
答案 0 :(得分：1)
stats API包含所谓的nested文档，因为在映射中标记为nested的字段被视为自己的lucene文档，其中count count只计算顶级对象
