• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach ky) OR (sac ky)) lang van hoi. hieu va nam thuc va ((dan vai) or (dan va)) cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sac ky)) lang van hoi. hieu va nam thuc va ((dan vai) OR (dan va)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) OR (sac ky)) lang van hoi. hieu va nam thuc va ((dan vai) or (dan va)) cau treo".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) OR (sac ky)) lang van hoi. hieu va nam thuc va ((dan vai) or (dan va)) cau treo*.
