• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang jane a ((gender cong) OR (gender change)) ((van one) OR (van onze)) saur ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang jane a ((gender cong) OR (gender change)) ((van one) or (van onze)) saur ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang jane a ((gender cong) OR (gender change)) ((van one) or (van onze)) saur ;*.
