Hi, I'm doing some load testing and I found something strange on ElasticSearch (2.2.0). I feed a single index with 104.690.000 documents. This index has only 2 shards. When I check the output of `/_cat/indices`, I get this: `green open customer-data-100m-v1 2 1 104690000 0 171.2gb 88.3gb` But when I do a `GET /customer-data-100m-v1/customer/_count`, I get half number of documents: `{ "count": 52345000, "_shards": { "total": 2, "successful": 2, "failed": 0 } }` Is this somehow related to the number of shards? Shouldn't I get the same count? ---

What happens if you `GET /customer-data-100m-v1/_count` instead of `GET /customer-data-100m-v1/customer/_count` ---

I get the same output. ---

So, it looks like it's not related to the number of shards, because I loaded another index with +100mi docs, but now with 4 shards, and I also get half count. `green open customer-data-100m-4shards-v1 4 1 107180000 0 171gb 85.5gb` `{ "count": 53590000, "_shards": { "total": 4, "successful": 4, "failed": 0 } }` ---

I deleted a few docs to try something else, so here are the updated results, including the part of the output of `/_stats` ```auto green open customer-data-100m-v1 2 1 104677426 12574 170.9gb 88gb ``` ```auto { "count": 52338713, "_shards": { "total": 2, "successful": 2, "failed": 0 } } ``` The the output of `/customer-data-100m-v1/_stats` is at [http://pastebin.com/raw/YpZn06jK](http://pastebin.com/raw/YpZn06jK) ---

\_stats gave you the number you expected ```auto "indices": { "customer-data-100m-v1": { "primaries": { "docs": { "count": 104677426, "deleted": 12574 }, ``` but it's strange that \_count did not give you the same number. I checked many of my indices, and all gave the same number for both \_count and \_stats ---

Yes, but what is `count` then? ```auto { "count": 52338713, ``` ---

You previous \_count showed a total of two shards while the \_stats showed 4 shards. Could you try ```auto GET _cat/count/customer-data-100m-v1 ``` ---

At an educated guess, `_cat` include replica documents while `_stats` doesn't. ---
