Elastic search document count

Question

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

you may have docs in some other type in same index, try GET index/_count to confirm — Pandiyan Cool
{ "count": 9998, "_shards": { "total": 5, "successful": 5, "failed": 0 } } I am getting the same 9998. When i give GET index/_count — backtrack

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.
