##### suppose I have a two alias index,created by the template alias.

```auto
a_wm_201901 alias to wm_201901
b_wm_201901 alias to wm_201901

##returns nothing when query like below
{"index":"a_wm_201901","type":"doc","body":{"sort":[{"id":{"order":"desc"}}],"from":0,"size":25,"_source":["*"]},"ignore_unavailable":true} 

##returns the correct documents
{"index":"wm_201901","type":"doc","body":{"sort":[{"id":{"order":"desc"}}],"from":0,"size":25,"_source":["*"]},"ignore_unavailable":true} 

```

Enviroment:

docker-elk,with the both latest version(6.5.4) elk.  
Only one node elasticsearch,each index have 3 primary shard,no replicate.

Can anybody tell why this happen? Is there something I forget or made a mistake?

are you using security features? If so, maybe you are only allowed to read that index.

If you are not, we would greatly appreciate a **full** reproduction, starting with index/alias creation, document indexing and then the full queries.

Thanks!

The truth is I was using template index,It's all because of the filter term,I should specify it `keyword`

The conclusion is when you use template index do make sure your filter works.

```auto
  "aliases": {
      "a_{index}" : {
            "filter" : {
                "term" : {"company" : "a" }/* if the company is not specified as keyword,here you should use company.keyword instead */
            }
      },
      "b_{index}" : {
            "filter" : {
                "term" : {"company" : "b" }
            }
      }
  }

```
