• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang jane ((e gender) OR (1 gender)) ((congo call) OR (long call)) me saur ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang jane ((e gender) or (1 gender)) ((congo call) OR (long call)) me saur ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang jane ((e gender) or (1 gender)) ((congo call) OR (long call)) me saur ;*.
