• Performing a fuzzy search may retrieve terms with similar spellings: su cac ky ((dang xa) or (lang xa)) hoi. ((hieu van) OR (thien van)) chat xuc van thanh san cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac ky ((dang xa) OR (lang xa)) hoi. ((hieu van) OR (thien van)) chat xuc van thanh san cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ky ((dang xa) or (lang xa)) hoi. ((hieu van) OR (thien van)) chat xuc van thanh san cuu tre".
• Adding a wildcard symbol may retrieve word variants: su cac ky ((dang xa) or (lang xa)) hoi. ((hieu van) OR (thien van)) chat xuc van thanh san cuu tre*.
