• If you are trying to use Boolean operators, they must be ALL CAPS: wang tan yong ((((yuan chang) OR (huang chang))) OR (yang yang)) yang xi ((chang ha) OR (hong g)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang tan yong ((((yuan chang) OR (huang chang))) or (yang yang)) yang xi ((chang ha) or (hong g)) ;".
• Adding a wildcard symbol may retrieve word variants: wang tan yong ((((yuan chang) OR (huang chang))) or (yang yang)) yang xi ((chang ha) or (hong g)) ;*.
