• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((anh nang) OR (ganh nang)) dua thong huong ((dan than) OR (dan chan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((anh nang) OR (ganh nang)) dua thong huong ((dan than) or (dan chan)) cao".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((anh nang) OR (ganh nang)) dua thong huong ((dan than) or (dan chan)) cao*.
