• Performing a fuzzy search may retrieve terms with similar spellings: nuoc ((sac ky) OR (sai ky)) nang lai hoa. ((hieu ve) or (hieu van)) cam xuc va hanh va cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc ((sac ky) OR (sai ky)) nang lai hoa. ((hieu ve) OR (hieu van)) cam xuc va hanh va cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc ((sac ky) OR (sai ky)) nang lai hoa. ((hieu ve) or (hieu van)) cam xuc va hanh va cua triet".
• Adding a wildcard symbol may retrieve word variants: nuoc ((sac ky) OR (sai ky)) nang lai hoa. ((hieu ve) or (hieu van)) cam xuc va hanh va cua triet*.
