• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yang) OR (yang yang)) ((han when) OR (han shen)) chang ann hong yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) OR (yang yang)) ((han when) or (han shen)) chang ann hong yu ;*".
