I'm trying to find documents where the `host.os.platform` field has some words similar to `host.os.name` for example I want to use Kibana discover either Lucene or KQL for that.  
This is what I came up with :

```auto
host.os.platform:*host.os.name*

```

This query uses a wildcard character `*` to match any characters before or after the value of `host.os.name` . So if `host.os.name` is "Rocky Linux", this query will match documents where `host.os.platform` contains any words that include "Rocky", such as "rocky", "rockylinux", "rocky-8", etc.

I m not getting results can any one may be advise on what I m doing wrong here.

update some thing what I came up with may it will help some one

```auto
host.name: *linux* and host.os.type: linux

```

Hi @Tiharqa. It looks like you have figured out the solution. I would only add that `*linux*` can be a very resource intensive query because the pattern begins with the wildcard character `*` . Note the Warning in [this documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html).
