• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((thu nang) OR (thu hang)) xa hoi. hieu ve chat tuc va tinh lai ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((thu nang) OR (thu hang)) xa hoi. hieu ve chat tuc va tinh lai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thu nang) OR (thu hang)) xa hoi. hieu ve chat tuc va tinh lai ((cua tre) or (cuu tre))*".
