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