• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ty) OR (sach thu)) nang x hoi. hieu va cac xuc va van dai ((cua triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach thu)) nang x hoi. hieu va cac xuc va van dai ((cua triet) OR (cua viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach thu)) nang x hoi. hieu va cac xuc va van dai ((cua triet) or (cua viet))*".
