• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ky cong) OR (ke cong)) ha hoi. hieu ((van cau) or (van nam)) duc van hanh ca chua trieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky cong) OR (ke cong)) ha hoi. hieu ((van cau) OR (van nam)) duc van hanh ca chua trieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky cong) OR (ke cong)) ha hoi. hieu ((van cau) or (van nam)) duc van hanh ca chua trieu".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky cong) OR (ke cong)) ha hoi. hieu ((van cau) or (van nam)) duc van hanh ca chua trieu*.
