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