• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty hang van hoc. thien ((van cam) OR (van nam)) ((xuc va) or (tuc va)) hanh de cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty hang van hoc. thien ((van cam) OR (van nam)) ((xuc va) OR (tuc va)) hanh de cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty hang van hoc. thien ((van cam) OR (van nam)) ((xuc va) or (tuc va)) hanh de cua triet".
• Adding a wildcard symbol may retrieve word variants: so sach ty hang van hoc. thien ((van cam) OR (van nam)) ((xuc va) or (tuc va)) hanh de cua triet*.
