• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) tinh - manh truong dai khung duong va ((toan ban) OR (toan tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) tinh - manh truong dai khung duong va ((toan ban) or (toan tap))".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) tinh - manh truong dai khung duong va ((toan ban) or (toan tap))*.
