• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((lang ha) or (dang xay)) hoi. hieu van nam xuc ban hang ((vi cua) OR (di cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang ha) OR (dang xay)) hoi. hieu van nam xuc ban hang ((vi cua) OR (di cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang ha) or (dang xay)) hoi. hieu van nam xuc ban hang ((vi cua) OR (di cua)) tre*".
