• Performing a fuzzy search may retrieve terms with similar spellings: tu sac kho tang dai hoi. hieu va chat xuc ((((va hanh) OR (va thanh))) or (van hanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac kho tang dai hoi. hieu va chat xuc ((((va hanh) OR (va thanh))) OR (van hanh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac kho tang dai hoi. hieu va chat xuc ((((va hanh) OR (va thanh))) or (van hanh)) vi cua tre*".
