Multiple dataset fields lookup

Question

This is an example of using a Spry region to implement Zuggest like results.
http://labs.adobe.com/technologies/spry/samples/data_region/ZuggestSample.html
However, I want the text can be searched into multiple fields in the dataset.
I simply tried adding a "category" to the array of fields to be searched
and hope the array should be passed as the fifth argument.
But It doesn't work~~

Before
=====
<script language="JavaScript" type="text/javascript">
var ac2 = new Spry.Widget.SimpleAutoSuggest("productTF", "productMenu", function(acWidget, str) { MyQueryFunc(acWidget, str, document.getElementById("productCB").checked, dsProducts, "name"); });
</script>

After
====
<script language="JavaScript" type="text/javascript">
var ac2 = new Spry.Widget.SimpleAutoSuggest("productTF", "productMenu", function(acWidget, str) { MyQueryFunc(acWidget, str, document.getElementById("productCB").checked, dsProducts, {"name","category"}); });
</script>

Try
// FilterData() and StartFilterTimer()
function MyQueryFunc() {
    var tf = document.getElementById("productTF");
    if (!tf.value)
        // If the text field is empty, remove any filter
        // that is set on the data set.
        dsProducts.filter(null);
        return;
    // Set a filter on the data set that matches any row
    // that begins with the string in the text field.
    var regExpStr = tf.value;
    if (!document.getElementById("productCB").checked)
        regExpStr = "^" + regExpStr;  
    var regExp = new RegExp(regExpStr, "i");
    var filterFunc = function(ds, row, rowNumber)
        var str = row["name"];
        if (str && str.search(regExp) != -1)
            return row;
        var str = row["category"];
        if (str && str.search(regExp) != -1)
            return row;
        return null;
    dsProducts.filter(filterFunc);
function StartFilterTimer() {
    if (StartFilterTimer.timerID)
        clearTimeout(StartFilterTimer.timerID);
    StartFilterTimer.timerID = setTimeout(function() { StartFilterTimer.timerID = null; MyQueryFunc(); }, 100);
