1)我有一个索引“数据”，其中包含479427个文档。为了得到我使用过的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检查了，得到的响应是这样的{
"count": 479427,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
}
}
从1和2开始，文章数相同。
但是当我尝试
GET /data/_stats命令时，我在get和total字段中得到的计数不同。"data": {

我什至通过提供
curator_cli show_indices --verbose来检查策展人的情况，它给出了如下响应:data open 11.1GB 4814308 5 1 2017-05-31T13:00:37Z为什么会有差异？
更新----------------------
1)您是说stats API将嵌套的每个字段都视为文档，对吗？
注意:
BTW I am talking about the total.docs.count field in stats api。2)where count API将基于唯一ID给出索引中存在的文档数。
所以我的问题是，我是否想知道索引中存在多少个文件，api会正确地计数
count，get，stats或curator_cli show_indices --verbose(使用策展人)？谢谢
最佳答案
stats API包括所谓的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，而count API只是在对顶级对象进行计数。
关于elasticsearch - Count和Stats API在Elasticsearch中显示不同的文档计数？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44899246/
