• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ty nang ma hoa. hieu va cao xuc ((va danh) or (va dinh)) ((vi cua) OR (di cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty nang ma hoa. hieu va cao xuc ((va danh) OR (va dinh)) ((vi cua) OR (di cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty nang ma hoa. hieu va cao xuc ((va danh) or (va dinh)) ((vi cua) OR (di cua)) te*".
