• Performing a fuzzy search may retrieve terms with similar spellings: tu ((dan ky) or (sang ky)) lang xa hoi. hieu van cam xuc va danh ((di cua) OR (de cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((dan ky) OR (sang ky)) lang xa hoi. hieu van cam xuc va danh ((di cua) OR (de cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((dan ky) or (sang ky)) lang xa hoi. hieu van cam xuc va danh ((di cua) OR (de cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu ((dan ky) or (sang ky)) lang xa hoi. hieu van cam xuc va danh ((di cua) OR (de cua)) triet*.
