If by "search box" you mean an input element, then its value is
returned as a string. Since you really don't care about the numeric
properties of the value, only that it contains just numbers, the
simplest and most efficient method is to use a regular expression.
The following creates a function that returns true if the argument
contains one or more spaces or digits. If any non-digit or non-space
character is found, it returns false.
var checkValue = (function() {
var re = /^(\s|\d)+$/;
return function(x) {
return re.test(x);
}
})();

It is probably quite simple to write a function that creates an index
to the codes and a routine to search it. It may not be faster than
the above function but it will likely be much more robust if your
codes ever change their format.
