• If you are trying to use Boolean operators, they must be ALL CAPS: (((wang OR wan) yanling) OR (yang yang)) y hua lee sang minh ((jeong hai) OR (jeong han)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((wang OR wan) yanling) or (yang yang)) y hua lee sang minh ((jeong hai) or (jeong han)) ;*".
