• Performing a fuzzy search may retrieve terms with similar spellings: ((wang zheng) OR (wang zhenpo)) dong ((yu chen) or (jui chen)) ping ku ((wang he) or (wong yue)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang zheng) OR (wang zhenpo)) dong ((yu chen) OR (jui chen)) ping ku ((wang he) OR (wong yue)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang zheng) OR (wang zhenpo)) dong ((yu chen) or (jui chen)) ping ku ((wang he) or (wong yue)) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang zheng) OR (wang zhenpo)) dong ((yu chen) or (jui chen)) ping ku ((wang he) or (wong yue)) ;*.
