• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) yan yang ((ai test) OR (ii test)) housking a ((kong saur) OR (dong skin)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR lang) yan yang ((ai test) or (ii test)) housking a ((kong saur) or (dong skin)) ;".
• Adding a wildcard symbol may retrieve word variants: (wang OR lang) yan yang ((ai test) or (ii test)) housking a ((kong saur) or (dong skin)) ;*.
