• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((da nang) OR (kha nang)) ((ma hoi) or (mai hoi)). hieu ve cam duc va hang hai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((da nang) OR (kha nang)) ((ma hoi) OR (mai hoi)). hieu ve cam duc va hang hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((da nang) OR (kha nang)) ((ma hoi) or (mai hoi)). hieu ve cam duc va hang hai cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ((da nang) OR (kha nang)) ((ma hoi) or (mai hoi)). hieu ve cam duc va hang hai cua te*.
