• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((chieu xanh) or (chieu sang)) - hanh trung vap ((nhung duong) OR (nhung tuong)) van tan ca~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sang)) - hanh trung vap ((nhung duong) OR (nhung tuong)) van tan ca*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sang)) - hanh trung vap ((nhung duong) OR (nhung tuong)) van tan ca*".
