• Performing a fuzzy search may retrieve terms with similar spellings: ((te cach) OR (te sach)) tru nang ((cho hoc) or (khoa hoc)). hieu van cam xuc van hanh vi cua cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cach) OR (te sach)) tru nang ((cho hoc) OR (khoa hoc)). hieu van cam xuc van hanh vi cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cach) OR (te sach)) tru nang ((cho hoc) or (khoa hoc)). hieu van cam xuc van hanh vi cua cau*".
