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