• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((dang van) OR (hang va)) hoe. hieu van nam xuc va hanh ((vi cua) or (di cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((dang van) OR (hang va)) hoe. hieu van nam xuc va hanh ((vi cua) OR (di cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((dang van) OR (hang va)) hoe. hieu van nam xuc va hanh ((vi cua) or (di cua)) triet*".
