• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan jan) or (yan yuan)) a ((gender truong) OR (gender typing)) thanh done saul ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan jan) or (yan yuan)) a ((gender truong) OR (gender typing)) thanh done saul ;*.
