• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (vu sach)) ky nang o hoi. lieu va cau xuc ((van hanh) OR (ban hanh)) ca cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (vu sach)) ky nang o hoi. lieu va cau xuc ((van hanh) OR (ban hanh)) ca cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (vu sach)) ky nang o hoi. lieu va cau xuc ((van hanh) OR (ban hanh)) ca cua te".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (vu sach)) ky nang o hoi. lieu va cau xuc ((van hanh) OR (ban hanh)) ca cua te*.
