If I understand your question correctly:

use the blur-Eventhandler instead of the keyUp Eventhandler. That way your Event will only be triggered if the user leaves the inputfield with which he's trying to search.

So instead of:

$("selector").keyUp(function(e) {  your ajaxCode; }

Try:

$("selector").blur(function(e) { your ajax Code; }

use change

$('#selecter').change(function(){

    var val = $(this).val();

    $.ajax({
     type: "POST",
     url: "some.php",
     data: {value=val},
     success: function(msg){
     alert(msg);
       }
    });    
});
