• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) or (su cac)) ky ((nang xa) OR (lang xa)) hoi. hieu ve cap nguoi va hang dien cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky ((nang xa) OR (lang xa)) hoi. hieu ve cap nguoi va hang dien cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su cac)) ky ((nang xa) OR (lang xa)) hoi. hieu ve cap nguoi va hang dien cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su cac)) ky ((nang xa) OR (lang xa)) hoi. hieu ve cap nguoi va hang dien cua tre*.
