### Steps to Reproduce

Steps to recreate issue.
From kibana add sample data sets ['Sample flight data','Sample eCommerce orders']
Create dataview
name:test
index patter:kibana_*
timefield: --- I don't want to use the time filter ---

From discover sort by AvgTicketPrice, or run query
```
POST kibana_*/_search
{
    "sort": [
        {
            "AvgTicketPrice": {
                "order": "desc",
                "unmapped_type": "boolean"
            }
        }
    ],
    "fields": [
        {
            "field": "*",
            "include_unmapped": "true"
        }
    ],
    "size": 500
}
```
Can't sort on field [AvgTicketPrice]; the field has incompatible sort types: [LONG] and [FLOAT] across shards!
