• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu xanh) OR (chieu sach)) - ((hanh tang) or (anh tang)) cua hang cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - ((hanh tang) OR (anh tang)) cua hang cong dan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - ((hanh tang) or (anh tang)) cua hang cong dan toan cau*".
