• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sach - ((hinh trong) OR (anh truong)) cao thong thong ((ban chat) OR (bao chat)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - ((hinh trong) or (anh truong)) cao thong thong ((ban chat) OR (bao chat)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu sach - ((hinh trong) or (anh truong)) cao thong thong ((ban chat) OR (bao chat)) ban*.
