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