• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu sach) OR (thien hach)) - ((hanh hang) OR (hanh han)) ca nhung cong dan phan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu sach) or (thien hach)) - ((hanh hang) OR (hanh han)) ca nhung cong dan phan cau*".
