A simple implementation of a delayed search with jQuery and Ajax

delayedsearch.js

var ReverseSearch = {
    onReady: function(){
        $("#rsearch input").on("keyup change", ReverseSearch.wait);
    },
    wait: function(e){
        clearTimeout($.data(this, 'timer'));
        if (e.keyCode == 13){
            ReverseSearch.rsearch(true);
        } else {
          $(this).data('timer', setTimeout(ReverseSearch.rsearch, 500));
        }
    },
    rsearch: function(){
        var raddress = $("#rsearch input[name='address']").val(),
            rstate = $("#rsearch input[name='state']").val();
        $.post("ajaxScripts/if-address-reverse-search-ajax.php", { address: raddress, state: rstate })
        .done(function(data){
            var results = $("<div/>", {
                html: data
            });
            $("#rsearch-results").html(results);
        });
    }
};
$(document).ready(ReverseSearch.onReady);
