• Performing a fuzzy search may retrieve terms with similar spellings: ((theo trieu) OR (theo chieu)) tinh - ((doanh ban) or (can ban)) va nhung cong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo trieu) OR (theo chieu)) tinh - ((doanh ban) OR (can ban)) va nhung cong dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo trieu) OR (theo chieu)) tinh - ((doanh ban) or (can ban)) va nhung cong dan than cau".
• Adding a wildcard symbol may retrieve word variants: ((theo trieu) OR (theo chieu)) tinh - ((doanh ban) or (can ban)) va nhung cong dan than cau*.
