• Performing a fuzzy search may retrieve terms with similar spellings: ((((thuat sach) OR (thuat san))) or (su sach)) ty hang x ho. hieu ve chao tu van hanh lai cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((thuat sach) OR (thuat san))) OR (su sach)) ty hang x ho. hieu ve chao tu van hanh lai cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((thuat sach) OR (thuat san))) or (su sach)) ty hang x ho. hieu ve chao tu van hanh lai cua vat*".
