• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty hang xa hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh vai ((cua tre) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty hang xa hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh vai ((cua tre) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty hang xa hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh vai ((cua tre) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: su sach ty hang xa hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh vai ((cua tre) or (cua viet))*.
