I have a few different indices, each of which have a different data type that they represent. Each of these data types are related.

For Example

Issue Index,  
Tag Index,  
Audit Trail Index.

Each with a single data type . (Issue, Tag, Audit Entry)

Each of these data types has a case\_id field, and a number of other fields related to that data type.

I would like to have a Dashboard where I can do something like the below.

Filter on Tag by a field that only exists in the Tag index (Tagger for example).  
Select All Case\_ID by that filter.  
Filter Issues by those case ids.

Is this possible? This would be similar to what in SQL would look like  
SELECT \* FROM issues WHERE case\_id in (SELECT case\_id FROM tags WHERE tagger = 'jon smith');

Hey @misiakj,

If you were to create documents similar to the following:

```auto
POST countries/_doc
{
  "country": "USA"
}

POST countries/_doc
{
  "country": "CN"
}

POST countries/_doc
{
  "country": "BZ"
}

POST municipalities/_doc
{
  "name": "California",
  "country": "USA"
}

POST municipalities/_doc
{
  "name": "Texas",
  "country": "USA"
}

POST municipalities/_doc
{
  "name": "California",
  "country": "USA"
}

POST municipalities/_doc
{
  "name": "São Paulo",
  "country": "BZ"
}

POST municipalities/_doc
{
  "name": " Brasília",
  "country": "BZ"
}

POST municipalities/_doc
{
  "name": "Shanghai",
  "country": "CN"
}

POST municipalities/_doc
{
  "name": " Beijing",
  "country": "CN"
}

```

Then you could create two index patterns, one for Countries and one for Municipalities.

Then you can create two Visualizations, one which is the "Input Control" defined like so:

And then if you added both to a Dashboard, you could use the Input Controls visualization to filter which Municipalities are shown:
