I am using ELK version 8.12.0. I have a field called

> 'request.querystring.username'

and that field has different data types keyword and boolean in different indices.

- Why the same field has the same different data types in different indices?
- How to list the indices which contains the boolean data type for that field?
- How to fix the data type as keyword for the same field in the future?

Hello

1. This could be an index mapping problem, try GET \<index\_name\>/mapping for each index to check how the fields are being mapped to
2. reindex and into a new index and change the alias name to the old index name
3. You can have a look into dynamic mapping or setting up an index template so that field will be mapped as a keyword in future data ingestions

```auto
GET index_name/_mapping

```

or

```auto
GET index_name/_mapping/field/request

```

either create component template or just recreate the index template  
again set the mapping for that particular object request

```auto
"request": {
    "properties":{
         "querystring": {
             "properties": {
                  "username" : {
                      "type":"keyword" 
                  }
             }
          }
     }
}

```

and reindex the data after completely deleting the existing index
