• Performing a fuzzy search may retrieve terms with similar spellings: su sach y hang tai hoc. hieu ve cham xuc ((((van hanh) OR (ban hanh))) or (van anh)) vi cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y hang tai hoc. hieu ve cham xuc ((((van hanh) OR (ban hanh))) OR (van anh)) vi cua tuc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y hang tai hoc. hieu ve cham xuc ((((van hanh) OR (ban hanh))) or (van anh)) vi cua tuc*".
