• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) guang vu ((((jie zhang) OR (bin zhang))) OR (li zhang)) li song min ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang yan)) guang vu ((((jie zhang) OR (bin zhang))) or (li zhang)) li song min ;*".
