• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky nang ((ma hoi) OR (xa hoi)). hieu ve bao suc van thanh ((hai cua) or (thai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky nang ((ma hoi) OR (xa hoi)). hieu ve bao suc van thanh ((hai cua) OR (thai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang ((ma hoi) OR (xa hoi)). hieu ve bao suc van thanh ((hai cua) or (thai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang ((ma hoi) OR (xa hoi)). hieu ve bao suc van thanh ((hai cua) or (thai cua)) triet*.
