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