Hide table rows until search is performed

I have a basic SearchBar attached to a basic TableView. It works fine, but I don't want any table rows to display until the user starts typing in the search bar, so it is always filtered, and never will ALL matching rows display in the table.

var searchbar = Ti.UI.createSearchBar();
 
var tv = Ti.UI.createTableView({
        data: myData,
        search: searchbar,
        hideSearchOnSelection: false,
        filterAttribute: 'title',
});
