• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((((tan chia) OR (than china))) OR (tan puay)) li zhang xin song shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((tan chia) OR (than china))) or (tan puay)) li zhang xin song shin ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((tan chia) OR (than china))) or (tan puay)) li zhang xin song shin ;*.
