• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thieu xanh) OR (hieu manh)) - ((hanh trang) or (hanh trinh)) xuan trung cong tap doan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (hieu manh)) - ((hanh trang) OR (hanh trinh)) xuan trung cong tap doan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (hieu manh)) - ((hanh trang) or (hanh trinh)) xuan trung cong tap doan cao*".
