Limit the API request

At least for as long as we’re still using Autocomplete version 0.38.x, then this solution should allow for specifying a minLength configuration option.

For example, in this highlighted section at https://github.com/WebDevStudios/wp-search-with-algolia/blob/main/templates/autocomplete.php#L158-L166

You’d want to add something like this:

var config = {
	minLength: 3,
	debug: algolia.debug,
	hint: false,
	openOnFocus: true,
	appendTo: 'body',
	templates: {
		empty: wp.template( 'autocomplete-empty' )
	}
};

I put the minLength at the top for easy viewing.

You’ll want to copy our autocomplete.php file template into your theme before making any changes, so that future updates don’t overwrite your changes. You can see how to do template customizations over at https://github.com/webDevStudios/wp-search-with-algolia/wiki/Customize-the-Autocomplete-dropdown
