• Performing a fuzzy search may retrieve terms with similar spellings: toc sac ky lang xa hoi. hieu va tham nuoc ban hanh vi ((cua tre) or (((cua triet) OR (su triet))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky lang xa hoi. hieu va tham nuoc ban hanh vi ((cua tre) OR (((cua triet) OR (su triet)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky lang xa hoi. hieu va tham nuoc ban hanh vi ((cua tre) or (((cua triet) OR (su triet))))".
• Adding a wildcard symbol may retrieve word variants: toc sac ky lang xa hoi. hieu va tham nuoc ban hanh vi ((cua tre) or (((cua triet) OR (su triet))))*.
