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