• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sai) OR (tu cai)) ky nang xa hoi. thien van phan duc ban hanh vai ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sai) OR (tu cai)) ky nang xa hoi. thien van phan duc ban hanh vai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sai) OR (tu cai)) ky nang xa hoi. thien van phan duc ban hanh vai ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: ((tu sai) OR (tu cai)) ky nang xa hoi. thien van phan duc ban hanh vai ((cua tre) or (cua triet))*.
