• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ty) OR (sach thu)) xang xa hoi. hieu van cac xuc van dinh ((vi cua) or (di cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach thu)) xang xa hoi. hieu van cac xuc van dinh ((vi cua) OR (di cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) OR (sach thu)) xang xa hoi. hieu van cac xuc van dinh ((vi cua) or (di cua)) te*".
