• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sang - hanh tranh cua ((thong cong) OR (tong cong)) dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sang - hanh tranh cua ((thong cong) OR (tong cong)) dan toan ban*.
