• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien hach - ((hanh trang) OR (thanh trung)) ((cua dung) OR (cua dong)) cong ngang hang dau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien hach - ((hanh trang) or (thanh trung)) ((cua dung) OR (cua dong)) cong ngang hang dau*".
