• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu ((mang xa) or (ang xa)) hoi. thien van nam cua van thanh vai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu ((mang xa) OR (ang xa)) hoi. thien van nam cua van thanh vai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu ((mang xa) or (ang xa)) hoi. thien van nam cua van thanh vai ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach thu ((mang xa) or (ang xa)) hoi. thien van nam cua van thanh vai ((cua tre) OR (cua te))*.
