• If you are trying to use Boolean operators, they must be ALL CAPS: zhang jian ((wang liang) OR (yang judy)) li ((song hong) OR (song chong)) wang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang jian ((wang liang) or (yang judy)) li ((song hong) OR (song chong)) wang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: zhang jian ((wang liang) or (yang judy)) li ((song hong) OR (song chong)) wang zhi ;*.
