• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yan ((((1 gender) OR (2.1 gender))) OR (2 gender)) congo 2 money buy ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yan ((((1 gender) OR (2.1 gender))) or (2 gender)) congo 2 money buy ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yan ((((1 gender) OR (2.1 gender))) or (2 gender)) congo 2 money buy ;*.
