• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((((chieu xanh) OR (chieu sach))) or (chieu sang)) - manh trung hoc nhung cong dan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((chieu xanh) OR (chieu sach))) OR (chieu sang)) - manh trung hoc nhung cong dan than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((chieu xanh) OR (chieu sach))) or (chieu sang)) - manh trung hoc nhung cong dan than cau*".
