• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty lang van hoi. hieu van ((cac toc) OR (cac toi)) van doanh dan ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty lang van hoi. hieu van ((cac toc) or (cac toi)) van doanh dan ((cua te) OR (cua tu))*".
