• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty lang xa hoi. hieu ve cam duc va ((hanh tai) or (thanh tai)) ((cau treo) OR (cau triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty lang xa hoi. hieu ve cam duc va ((hanh tai) OR (thanh tai)) ((cau treo) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty lang xa hoi. hieu ve cam duc va ((hanh tai) or (thanh tai)) ((cau treo) OR (cau triet))".
• Adding a wildcard symbol may retrieve word variants: thu sach ty lang xa hoi. hieu ve cam duc va ((hanh tai) or (thanh tai)) ((cau treo) OR (cau triet))*.
