• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xiaoping) or (deng xiaoping)) ((tan chia) OR (than china)) daun yang mind data hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xiaoping) or (deng xiaoping)) ((tan chia) OR (than china)) daun yang mind data hai ;*.
