• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sach)) kho ((lang xa) OR (lang van)) hoi. hieu van nam xuc van hanh dan cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) kho ((lang xa) OR (lang van)) hoi. hieu van nam xuc van hanh dan cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) kho ((lang xa) OR (lang van)) hoi. hieu van nam xuc van hanh dan cua triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) kho ((lang xa) OR (lang van)) hoi. hieu van nam xuc van hanh dan cua triet*.
