• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky lang xa hoi. hieu ((ve cai) or (va cam)) truc ((va nang) OR (van nang)) di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang xa hoi. hieu ((ve cai) OR (va cam)) truc ((va nang) OR (van nang)) di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky lang xa hoi. hieu ((ve cai) or (va cam)) truc ((va nang) OR (van nang)) di cua te".
