hong than » hong tan, long thanh
qiang li » liang li, qiang niu, ling li
yang lin » yang jin, wang lin, yang li

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yuan) OR (fang yuan)) fei yi chen ((qiang li) OR (yang lin)) ((hong than) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yuan) or (fang yuan)) fei yi chen ((qiang li) or (yang lin)) ((hong than) OR (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yuan) or (fang yuan)) fei yi chen ((qiang li) or (yang lin)) ((hong than) OR (hong hai)) ;*.
