• Performing a fuzzy search may retrieve terms with similar spellings: te sach thu hang x ho. hieu van ((cac duc) OR (cac du)) va thanh hai ((cua tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu hang x ho. hieu van ((cac duc) OR (cac du)) va thanh hai ((cua tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu hang x ho. hieu van ((cac duc) OR (cac du)) va thanh hai ((cua tre) or (cau treo))*".
