• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) OR (tu sach)) ky nang xa hoi. hieu va nam truc va tinh voi ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky nang xa hoi. hieu va nam truc va tinh voi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky nang xa hoi. hieu va nam truc va tinh voi ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu sach)) ky nang xa hoi. hieu va nam truc va tinh voi ((cua tre) or (cua te))*.
