• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (chieu sang)) - hanh tang lan phuong luong vat ((thanh cau) OR (nhanh cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) OR (chieu sang)) - hanh tang lan phuong luong vat ((thanh cau) or (nhanh cau))~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) OR (chieu sang)) - hanh tang lan phuong luong vat ((thanh cau) or (nhanh cau))*.
