• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) ky nang co hoi. hieu ((ve cham) or (ve chat)) xuc va hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky nang co hoi. hieu ((ve cham) OR (ve chat)) xuc va hanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky nang co hoi. hieu ((ve cham) or (ve chat)) xuc va hanh vi cuu tre*".
