I don't believe there is a way to do this with a raw selector. The contains selector is case sensitive and there doesn't appear to be a case insensitive version. I think the best approach is to use a filter that manually queries the object

var filt = function (unused) {
  $(this).text().toLowerCase().indexOf(txtSearch.toLowerCase()) !== -1;
};
