• If you are trying to use Boolean operators, they must be ALL CAPS: lang a fang 2 ((chin cheng) OR (china chang)) ((han phong) OR (hai phong)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang a fang 2 ((chin cheng) or (china chang)) ((han phong) OR (hai phong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: lang a fang 2 ((chin cheng) or (china chang)) ((han phong) OR (hai phong)) shu ;*.
