Version : Kibana 5.4.0

Kibana acknowledges 2 musts in 1 bool as an error.  
It says,

`Duplicate key "must" . Syntax error.`

Is this illegal?

When I exectue the query , the result is returned properly.

Yes.

```auto
"must" : [
	{"match" : {"message:" "localhost"}},
	{"match" : {
		"range": {
			"@timestamp" : {
				"lt" : "now/h"
			}
		}
	}
]

```

This is the proper syntax.
