• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) or (hoc hien)) xanh - manh ((tung cua) OR (trung cua)) nhung cong tan toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - manh ((tung cua) OR (trung cua)) nhung cong tan toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) xanh - manh ((tung cua) OR (trung cua)) nhung cong tan toan tap*".
