Hello,
you can also add a helper on the client side to throttle the requests,
e.g. with backbone/underscore [1] this looks like:
searchBarKeyUp: _.throttle(function (e) {
e.preventDefault();
var $input = $(e.currentTarget);
var val = $input.val();
if (e.which == 13 || val.length > 2 || val == '') {
this.searchValue = encodeURI(val);
//
this.setList();
}
},
600)

Br,
Max
