• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (doi chi)) xanh - hanh trang qua ((song trong) OR (sang trong)) van van cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chi)) xanh - hanh trang qua ((song trong) OR (sang trong)) van van cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chi)) xanh - hanh trang qua ((song trong) OR (sang trong)) van van cau*.
