• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yong)) ((yan yuan) OR (yan guan)) dan yang xi ((kang hay) OR (kang han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang yong)) ((yan yuan) or (yan guan)) dan yang xi ((kang hay) OR (kang han)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yong)) ((yan yuan) or (yan guan)) dan yang xi ((kang hay) OR (kang han)) ;*.
