Multiple keys: Return matches from both keys?

Sorry if I’m misunderstanding the documentation, but it looks to me from testing that if you specify multiple keys it will look for matches in one key or the other but not both. For example:

https://codepen.io/tarekraafat/pen/rNyBxdL

The data contains this:

    {
        "food": "Wild Boar - Tenderloin",
        "cities": "Luthu",
        "animals": "Eastern diamondback rattlesnake"
    },

A search for “wild” will return a result from that row, and a search for “luthu” will return a result from that row, but searching “wild luthu” will not return anything.

I’d like to be able to do a name search by firstname and surname so that a search for “owe leo” would return this row:

{
	"surname": "Leonard",
	"firstname": "Owen",
}

Is this currently possible?

new autoComplete({
	searchEngine: (q, r) => {
		if ( r.includes(q) ) {
			return r
		}
		return false
	}
})

If you don’t use config.data.keys like I said, then r will be the entire record instead of the property at the keys, so

new autoComplete({
	searchEngine: (q, r) => {
		if ( r.surname.includes(q) ) {
			return r.surname
		}
		if ( r.firstname.includes(q) ) {
			return r.firstname
		}
		return false
	}
})
