Search queries should throw validation error if unknown keys are used

[DrewImm]

Is your feature request related to a problem? Please describe.
When creating a query, if a query-type doesn't exist, no warning/error is thrown. Instead, the query-type is ignored

e.g: If you use were instead of where, it should throw an error:

{
	...
	"were": {
		...
	}
}

Describe the solution you'd like
The request should fail with a validation error
