• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((hieu manh) OR (hieu nganh))) OR (chieu sach)) - thanh tran van nang cong dan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((hieu manh) OR (hieu nganh))) or (chieu sach)) - thanh tran van nang cong dan toan cau*".
