It is much simpler than that, use the String.indexOf() function:

angular.forEach(items, function(item) {
    if( item.label.indexOf(searchText) >= 0 ) filtered.push(item);
});

You may want to turn both strings .toLowerCase() to do case-insensitive matching:

searchText = searchText.toLowerCase();
angular.forEach(items, function(item) {
    if( item.label.toLowerCase().indexOf(searchText) >= 0 ) filtered.push(item);
});
