• Performing a fuzzy search may retrieve terms with similar spellings: ho thieu quang - ((hanh dong) or (anh dang)) luan hung cong ((san toan) OR (dan toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho thieu quang - ((hanh dong) OR (anh dang)) luan hung cong ((san toan) OR (dan toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho thieu quang - ((hanh dong) or (anh dang)) luan hung cong ((san toan) OR (dan toan)) cau*".
