• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (toc thieu)) nganh - hanh trang cua nhung song van ((tuan cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) OR (toc thieu)) nganh - hanh trang cua nhung song van ((tuan cau) or (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) OR (toc thieu)) nganh - hanh trang cua nhung song van ((tuan cau) or (toan cau))*.
