• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thien) OR (hoc thieu)) anh - canh tranh ((va dung) OR (va duong)) truong thanh toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) or (hoc thieu)) anh - canh tranh ((va dung) OR (va duong)) truong thanh toan tap".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) or (hoc thieu)) anh - canh tranh ((va dung) OR (va duong)) truong thanh toan tap*.
