• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky lang xa hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh ((vi cua) or (di cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang xa hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh ((vi cua) OR (di cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky lang xa hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh ((vi cua) or (di cua)) te*".
