• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky tang ma hoi. hieu ((van cam) OR (van cau)) qua ban ((thanh vai) or (thanh tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky tang ma hoi. hieu ((van cam) OR (van cau)) qua ban ((thanh vai) OR (thanh tai)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky tang ma hoi. hieu ((van cam) OR (van cau)) qua ban ((thanh vai) or (thanh tai)) cua tre*".
