• Performing a fuzzy search may retrieve terms with similar spellings: ((((so sach) OR (co sach))) or (so sanh)) y nang xa hoi. hieu va can thuc va thanh ve cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((so sach) OR (co sach))) OR (so sanh)) y nang xa hoi. hieu va can thuc va thanh ve cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((so sach) OR (co sach))) or (so sanh)) y nang xa hoi. hieu va can thuc va thanh ve cua triet".
• Adding a wildcard symbol may retrieve word variants: ((((so sach) OR (co sach))) or (so sanh)) y nang xa hoi. hieu va can thuc va thanh ve cua triet*.
