• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc chieu) OR (hoc hien)) xanh - hanh trang ((cua thong) or (cua thuong)) tuong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc hien)) xanh - hanh trang ((cua thong) OR (cua thuong)) tuong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (hoc hien)) xanh - hanh trang ((cua thong) or (cua thuong)) tuong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (hoc hien)) xanh - hanh trang ((cua thong) or (cua thuong)) tuong dan toan cau*.
