• If you are trying to use Boolean operators, they must be ALL CAPS: zhang yan yan di ((((li cong) OR (li rong))) OR (((kim song) OR (kim young)))) fund congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan yan di ((((li cong) OR (li rong))) or (((kim song) or (kim young)))) fund congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yan yan di ((((li cong) OR (li rong))) or (((kim song) or (kim young)))) fund congo shu ;*.
