• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) OR (toc thieu)) tinh - manh luong qua dung cong ((manh toan) or (van hang)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) tinh - manh luong qua dung cong ((manh toan) OR (van hang)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) tinh - manh luong qua dung cong ((manh toan) or (van hang)) cau*".
