• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang zhang) OR (wang luhang)) ming ((runs out) OR (iran cost)) sharing test among eu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang zhang) OR (wang luhang)) ming ((runs out) or (iran cost)) sharing test among eu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang zhang) OR (wang luhang)) ming ((runs out) or (iran cost)) sharing test among eu ;*.
