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