• Performing a fuzzy search may retrieve terms with similar spellings: vu hai ky nang xa hoi. hieu ve nam thuoc ((va thanh) or (gia thanh)) ((vi cua) OR (vai cua)) tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu hai ky nang xa hoi. hieu ve nam thuoc ((va thanh) OR (gia thanh)) ((vi cua) OR (vai cua)) tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu hai ky nang xa hoi. hieu ve nam thuoc ((va thanh) or (gia thanh)) ((vi cua) OR (vai cua)) tu*".
