• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - thanh trung vap ((((nhung don) OR (nhung van))) OR (hang cong)) dan ca cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - thanh trung vap ((((nhung don) OR (nhung van))) or (hang cong)) dan ca cau*".
