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