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