• Performing a fuzzy search may retrieve terms with similar spellings: ((su cac) OR (su can)) ky nang x hoi. ((hieu van) or (thien van)) bao xuc va hanh chinh cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su cac) OR (su can)) ky nang x hoi. ((hieu van) OR (thien van)) bao xuc va hanh chinh cua tre.
