• Performing a fuzzy search may retrieve terms with similar spellings: toc ((((sach ty) OR (sach tu))) or (sach y)) nang cao hoc. hieu ve cac xuc van anh va cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((((sach ty) OR (sach tu))) OR (sach y)) nang cao hoc. hieu ve cac xuc van anh va cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((((sach ty) OR (sach tu))) or (sach y)) nang cao hoc. hieu ve cac xuc van anh va cua cau*".
