• Performing a fuzzy search may retrieve terms with similar spellings: ((wang wang) OR (wang yang)) ((dan con) or (man han)) ((lee chang) or (lee chung)) wang wong yue ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yang)) ((dan con) OR (man han)) ((lee chang) OR (lee chung)) wang wong yue ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yang)) ((dan con) or (man han)) ((lee chang) or (lee chung)) wang wong yue ;".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) OR (wang yang)) ((dan con) or (man han)) ((lee chang) or (lee chung)) wang wong yue ;*.
