I kinda think that caching should be applicable to all types of query not just filter. So may be it can be something like this
{code}
{
	"query": {
		"cache": {
			"query" : {
				"filter" : {
					///
				}
			}
		}
	}
}
{code}
By doing this, it gives to users the power on caching on any level of the query.
This is just my idea about syntax since I have not been able to look into QParsers and ExtensibleQuery deeply enough.

And it makes sense to me that all the nested {{filter}} queries inside {{bool}} should also be cached by default. So there are no different between using {{filter}} inside {{bool}} vs providing {{filters}} at the top level.
