• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu nang chon hoc. hieu van cau luc van hanh vai ((((cua cau) OR (cua chu))) or (cua cay))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu nang chon hoc. hieu van cau luc van hanh vai ((((cua cau) OR (cua chu))) OR (cua cay))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu nang chon hoc. hieu van cau luc van hanh vai ((((cua cau) OR (cua chu))) or (cua cay))*".
