• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang fan run ((tan yong) OR (tan yang)) ((del marcco) OR (del mar)) (hai OR hari) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang fan run ((tan yong) OR (tan yang)) ((del marcco) or (del mar)) (hai or hari) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang fan run ((tan yong) OR (tan yang)) ((del marcco) or (del mar)) (hai or hari) ;*.
