弹性搜索文件数 [英] Elastic search document count

问题描述

我有一个弹性搜索运行2.2版本。我已经创建了索引并加载了示例文档。我发现了一些问题。当我给

  GET索引/类型/ _count 
  

我得到正确答案

  {
count ：9998，
_shards：{
total：5，
successful：5，
failed：0 
} 
但是，当我看到使用 http：// IP：9200的东西时，
  



/ _cat / indices？v

 健康状况指数pri rep docs.count docs.deleted store。 size pri.store.size 
 yellow open index 5 1 79978 0 32.1mb 32.1mb 
  

哪里docs.count：79978.哪个是错的。

为什么我看到错误的值为的docs.count。确切文件计数为9998

解决方案

GET索引/类型/ _count 将返回顶级文档数。

docs.count 在 _cat / indices 返回所有文档的计数，包括为嵌套字段创建的人工文档。

这就是为什么你看到一个区别：

• 以前的计数（即9998）会告诉您索引中有多少 Elasticsearch文档，即有多少索引。


• 后一个计数（即79978）将告诉您索引中有多少个 Lucene文档。因此，如果一个ES文档包含一个包含5个子元素的嵌套字段，则会看到1个ES文档，但是6个Lucene文档。根据计数，您的每个ES文档中都有7到8个嵌套元素。
  
  

  I am having a Elastic search running 2.2 version. I have created index and loaded sample documents. I found some problem in it. When i give

  GET index/type/_count
  

  I am getting the correct answer

  {
     "count": 9998,
     "_shards": {
        "total": 5,
        "successful": 5,
        "failed": 0
     }
  }
  

  But when i see the things using http://IP:9200/_cat/indices?v

  health status index pri rep docs.count docs.deleted store.size pri.store.size     
  yellow open   index  5   1      79978            0     32.1mb         32.1mb 
  

  Where docs.count : 79978. Which is wrong.

  Why i am seeing docs.count with wrong value. The exact document count is 9998

  解决方案

  GET index/type/_count will return the top-level document count.

  docs.count in _cat/indices returns the count of all documents, including artificial documents that have been created for nested fields.

  That's why you see a difference:

  • The former count (i.e. 9998) will tell you how many Elasticsearch documents are in your index, i.e. how many you have indexed.
  • The latter count (i.e. 79978) will tell you how many Lucene documents are in your index.

  So if one ES document contain a nested field with 5 sub-elements, you'll see 1 ES document, but 6 Lucene documents. Judging by the counts, each of your ES document has between 7 and 8 nested elements within it.
