• Performing a fuzzy search may retrieve terms with similar spellings: doc ((hieu xanh) OR (chieu xanh)) - hanh mang cua truong cong tinh ((toan cau) or (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu xanh) OR (chieu xanh)) - hanh mang cua truong cong tinh ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) OR (chieu xanh)) - hanh mang cua truong cong tinh ((toan cau) or (toan cao))*".
