• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty lang xa hoi. hieu ve cham tuc va hanh lai ((((cua tre) OR (cua te))) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty lang xa hoi. hieu ve cham tuc va hanh lai ((((cua tre) OR (cua te))) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty lang xa hoi. hieu ve cham tuc va hanh lai ((((cua tre) OR (cua te))) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: tu sach ty lang xa hoi. hieu ve cham tuc va hanh lai ((((cua tre) OR (cua te))) or (cuu tre))*.
