• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((v nang) OR (va nang)) x hoi. thien van pham duc va danh ((di cua) or (vai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((v nang) OR (va nang)) x hoi. thien van pham duc va danh ((di cua) OR (vai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v nang) OR (va nang)) x hoi. thien van pham duc va danh ((di cua) or (vai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: te sach ((v nang) OR (va nang)) x hoi. thien van pham duc va danh ((di cua) or (vai cua)) triet*.
