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