Allow setting a threshold score for result to be considered a match

[thedivtagguy]

I'd like to be able to set a threshold on what is considered a match. This is what I do right now:

<Typeahead
	hideLabel
	label="Search works"
	placeholder="Try me..."
	{data}
	{extract}
	let:result
	let:value
>
	{#if result.score >= 20}
		<div>
			<strong>{getTitle(result.original)}</strong>
		</div>
	{/if}
</Typeahead>

This kinda works, but I still see empty boxes where the results below threshold are:

Allowing for something like this to be set so only very close matches are shown would be nice.
