• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sac) OR (vu san)) ky ((nang xa) or (nang x)) hoi. hieu he nam thu dan thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sac) OR (vu san)) ky ((nang xa) OR (nang x)) hoi. hieu he nam thu dan thanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sac) OR (vu san)) ky ((nang xa) or (nang x)) hoi. hieu he nam thu dan thanh vi cua te*".
