• If you are trying to use Boolean operators, they must be ALL CAPS: wang xiaodong chang chen ((e yang) OR (((pei yang) OR (wei yang)))) li zhang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang xiaodong chang chen ((e yang) or (((pei yang) OR (wei yang)))) li zhang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang xiaodong chang chen ((e yang) or (((pei yang) OR (wei yang)))) li zhang hari ;*.
