• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yan) OR (hong ng))) OR (dong di)) y ((n chen) OR (z chen)) xuan thang long shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yan) or (hong ng))) or (dong di)) y ((n chen) OR (z chen)) xuan thang long shu ;*".
