• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh v ((nang xa) OR (lang xa)) hoi. ((hieu van) or (thien van)) lam dua ban hanh va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh v ((nang xa) OR (lang xa)) hoi. ((hieu van) OR (thien van)) lam dua ban hanh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh v ((nang xa) OR (lang xa)) hoi. ((hieu van) or (thien van)) lam dua ban hanh va cua tre*".
