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