• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) or (toc thieu)) xanh - hanh trinh cua dang ((nong manh) OR (hoang manh)) toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (toc thieu)) xanh - hanh trinh cua dang ((nong manh) OR (hoang manh)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (toc thieu)) xanh - hanh trinh cua dang ((nong manh) OR (hoang manh)) toan cau*".
