• If you are trying to use Boolean operators, they must be ALL CAPS: man houng tan chia ban ((yan jiu) OR (yang jun)) ((((wong sau) OR (wong sam))) OR (kong sara)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "man houng tan chia ban ((yan jiu) or (yang jun)) ((((wong sau) OR (wong sam))) or (kong sara)) ;".
