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