• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. thi van cac xuc ((va thanh) or (ban thanh)) ((loi cua) OR (hoi cua)) viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. thi van cac xuc ((va thanh) OR (ban thanh)) ((loi cua) OR (hoi cua)) viet.
