• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang ((((wang hui) OR (wang he))) OR (wang wei)) sin jing ji cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ((((wang hui) OR (wang he))) or (wang wei)) sin jing ji cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ((((wang hui) OR (wang he))) or (wang wei)) sin jing ji cong shu ;*.
