• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((sang ma) OR (nang ma)) hoi. ((lieu van) or (lieu va)) cam duc ban hanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((sang ma) OR (nang ma)) hoi. ((lieu van) OR (lieu va)) cam duc ban hanh di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((sang ma) OR (nang ma)) hoi. ((lieu van) or (lieu va)) cam duc ban hanh di cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((sang ma) OR (nang ma)) hoi. ((lieu van) or (lieu va)) cam duc ban hanh di cua triet*.
