• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (((te sach) OR (toc sach)))) ty xang xa hoi. hieu ve cam tuc xa hanh va cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (((te sach) OR (toc sach)))) ty xang xa hoi. hieu ve cam tuc xa hanh va cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (((te sach) OR (toc sach)))) ty xang xa hoi. hieu ve cam tuc xa hanh va cua viet*".
