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