• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky bang cac phoi. hieu ((ve cam) or (ve cac)) duc va danh vi ((cua tu) OR (cua su))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky bang cac phoi. hieu ((ve cam) OR (ve cac)) duc va danh vi ((cua tu) OR (cua su))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky bang cac phoi. hieu ((ve cam) or (ve cac)) duc va danh vi ((cua tu) OR (cua su))*".
