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