How to put a delay on AngularJS instant search?

Question

I have a performance issue that I can\'t seem to address. I have an instant search but it\'s somewhat laggy, since it starts searching on each keyup().

Why does everyone wants to use watch? You could also use a function:

var tempArticleSearchTerm;
$scope.lookupArticle = function (val) {
    tempArticleSearchTerm = val;

    $timeout(function () {
        if (val == tempArticleSearchTerm) {
            //function you want to execute after 250ms, if the value as changed

        }
    }, 250);
};
