• Performing a fuzzy search may retrieve terms with similar spellings: ((((tu sac) OR (tu cac))) or (thuy san)) ky nang xa hoi. hieu van nam tu gia thanh vang cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sac) OR (tu cac))) OR (thuy san)) ky nang xa hoi. hieu van nam tu gia thanh vang cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sac) OR (tu cac))) or (thuy san)) ky nang xa hoi. hieu van nam tu gia thanh vang cua triet".
• Adding a wildcard symbol may retrieve word variants: ((((tu sac) OR (tu cac))) or (thuy san)) ky nang xa hoi. hieu van nam tu gia thanh vang cua triet*.
