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