• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ly ((lang xa) OR (lang van)) hoi. hieu va cam tuc ca dan hai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ly ((lang xa) OR (lang van)) hoi. hieu va cam tuc ca dan hai cau treo".
