• Performing a fuzzy search may retrieve terms with similar spellings: bo ((lieu tinh) OR (trieu tinh)) - ((lanh manh) or (canh tranh)) cua dang hong van tan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: bo ((lieu tinh) OR (trieu tinh)) - ((lanh manh) OR (canh tranh)) cua dang hong van tan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo ((lieu tinh) OR (trieu tinh)) - ((lanh manh) or (canh tranh)) cua dang hong van tan cau*".
