• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky lang van hoi. hieu ((ve cham) OR (va cham)) soc van ban vi ((cu tren) or (la tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky lang van hoi. hieu ((ve cham) OR (va cham)) soc van ban vi ((cu tren) OR (la tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky lang van hoi. hieu ((ve cham) OR (va cham)) soc van ban vi ((cu tren) or (la tren))*".
