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