• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu sang) OR (tiem nang)) - hanh mang ((cua thong) OR (cua thuong)) cong tac than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu sang) or (tiem nang)) - hanh mang ((cua thong) OR (cua thuong)) cong tac than cau".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu sang) or (tiem nang)) - hanh mang ((cua thong) OR (cua thuong)) cong tac than cau*.
