• If you are trying to use Boolean operators, they must be ALL CAPS: ((doc hieu) OR (toc thieu)) xanh - thanh tuong cua thuong thong ((dan toan) OR (manh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (toc thieu)) xanh - thanh tuong cua thuong thong ((dan toan) OR (manh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (toc thieu)) xanh - thanh tuong cua thuong thong ((dan toan) OR (manh toan)) cao*.
