• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - canh tranh cua ((nhung huong) OR (nhung phuong)) dan phan tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - canh tranh cua ((nhung huong) OR (nhung phuong)) dan phan tu".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - canh tranh cua ((nhung huong) OR (nhung phuong)) dan phan tu*.
