• Performing a fuzzy search may retrieve terms with similar spellings: te sach thue tang van hoi. hieu ((qua cac) or (cua cac)) duc va da thai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thue tang van hoi. hieu ((qua cac) OR (cua cac)) duc va da thai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thue tang van hoi. hieu ((qua cac) or (cua cac)) duc va da thai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach thue tang van hoi. hieu ((qua cac) or (cua cac)) duc va da thai ((cua tre) OR (cua triet))*.
