• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach xay) or (sach xa)) lang xa hoi. ((thien van) OR (thi van)) cam tu va thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach xay) OR (sach xa)) lang xa hoi. ((thien van) OR (thi van)) cam tu va thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach xay) or (sach xa)) lang xa hoi. ((thien van) OR (thi van)) cam tu va thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: su ((sach xay) or (sach xa)) lang xa hoi. ((thien van) OR (thi van)) cam tu va thanh vi cua te*.
