Hey,

we have different suppliers for data that is imported into elastic. The suppliers use different field names, but some of them use the same type of data.  
Example:  
Supplier A:  
last\_seen: 2020\_02\_03  
IP: 10.10.10.10

Supplier B:  
date: 2020\_02\_03  
ip\_address: 192.168.0.1

We have one index for each supplier. To simplify the search and to achieve some harmonisation I created alias fields.  
index A:  
date\_alias\_field =\> last\_seen  
ip\_alias\_field =\> IP

index B:  
date\_alias\_field =\> ip\_address  
ip\_alias\_field =\> ip\_address

The search works very well:

```
GET /_search
{
  "query": {
    "query_string": {
      "query": "192.168.0.1",
      "default_field": "ip_alias_field"
    }
  }
}

```

Now I want to use the alias fields, in this case the field "date\_alias\_field" for further steps in our process. But these are not output at all (because not part of "\_source"). Is there a solution to get them?

ps: we use "query\_string" because we have multiple alias fields and use wildcards (`*`), f.e. "default\_field": "ip\_alias\*"

Cheers  
Andreas

You can use a new [fields API](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-fields.html) that accepts alias fields as well:

```auto
{
  "query": <your_query>,
  "fields": ["date_alias_field", "ip_alias_field"]
}

```
