• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thieu xanh) or (thien danh)) - hanh tinh quang truong thuong ((dan toan) OR (van toan)) cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (thien danh)) - hanh tinh quang truong thuong ((dan toan) OR (van toan)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien danh)) - hanh tinh quang truong thuong ((dan toan) OR (van toan)) cao*".
