• Performing a fuzzy search may retrieve terms with similar spellings: su sach y lang xa hoi. ((hieu ve) OR (hieu va)) cam tuc ((va dinh) or (va tinh)) thai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y lang xa hoi. ((hieu ve) OR (hieu va)) cam tuc ((va dinh) OR (va tinh)) thai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y lang xa hoi. ((hieu ve) OR (hieu va)) cam tuc ((va dinh) or (va tinh)) thai cua tre*".
