• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((ky lang) OR (ky tang)) xa hoi. hieu ve cham xuc van thanh vi ((cau tren) or (ca tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((ky lang) OR (ky tang)) xa hoi. hieu ve cham xuc van thanh vi ((cau tren) OR (ca tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((ky lang) OR (ky tang)) xa hoi. hieu ve cham xuc van thanh vi ((cau tren) or (ca tren))".
• Adding a wildcard symbol may retrieve word variants: thu sach ((ky lang) OR (ky tang)) xa hoi. hieu ve cham xuc van thanh vi ((cau tren) or (ca tren))*.
