• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chieu)) xanh - canh tranh cua dang cong tac ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chieu)) xanh - canh tranh cua dang cong tac ((toan cao) OR (toan ban))*.
