• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh hang va dung trong ((((ty toan) OR (tam toan))) OR (tap toan)) tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh hang va dung trong ((((ty toan) OR (tam toan))) or (tap toan)) tap*".
