• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu anh - tinh ((nhan thuc) OR (dan thuc)) hung ((cong thai) OR (cong thaih)) phan cac.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu anh - tinh ((nhan thuc) OR (dan thuc)) hung ((cong thai) or (cong thaih)) phan cac".
• Adding a wildcard symbol may retrieve word variants: hoc thieu anh - tinh ((nhan thuc) OR (dan thuc)) hung ((cong thai) or (cong thaih)) phan cac*.
