• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (hoc anh)) ky nang xa hoi. hieu va nham thuc ((xa hanh) OR (xa khanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (hoc anh)) ky nang xa hoi. hieu va nham thuc ((xa hanh) OR (xa khanh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (hoc anh)) ky nang xa hoi. hieu va nham thuc ((xa hanh) OR (xa khanh)) vi cua triet*".
