• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((lang xa) OR (dang xay)) hoi. nhieu viec dao tuc va dat ((vi cua) or (di cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang xa) OR (dang xay)) hoi. nhieu viec dao tuc va dat ((vi cua) OR (di cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang xa) OR (dang xay)) hoi. nhieu viec dao tuc va dat ((vi cua) or (di cua)) triet".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang xa) OR (dang xay)) hoi. nhieu viec dao tuc va dat ((vi cua) or (di cua)) triet*.
