• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien danh - ((hanh trang) OR (thanh trung)) qua trong cong van ((thanh cau) OR (nhanh cau)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien danh - ((hanh trang) OR (thanh trung)) qua trong cong van ((thanh cau) or (nhanh cau))".
