• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty dang van hoe. ((hieu van) or (lieu va)) nam xuc ((va hanh) OR (van hanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dang van hoe. ((hieu van) OR (lieu va)) nam xuc ((va hanh) OR (van hanh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty dang van hoe. ((hieu van) or (lieu va)) nam xuc ((va hanh) OR (van hanh)) vi cua triet*".
