• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty sang ma hoi. hieu van cau ((((xuc va) OR (tuc va))) or (thuc day)) thanh tiep cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty sang ma hoi. hieu van cau ((((xuc va) OR (tuc va))) OR (thuc day)) thanh tiep cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty sang ma hoi. hieu van cau ((((xuc va) OR (tuc va))) or (thuc day)) thanh tiep cua te*".
