• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang ((ban oil) OR (can oil)) can lang li ((((hong hari) OR (zhong zhi))) OR (wong yue)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ((ban oil) OR (can oil)) can lang li ((((hong hari) or (zhong zhi))) or (wong yue)) ;".
• Adding a wildcard symbol may retrieve word variants: wang wang ((ban oil) OR (can oil)) can lang li ((((hong hari) or (zhong zhi))) or (wong yue)) ;*.
