• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. hieu viec cac lo va danh vai ((cua tre) or (((cua triet) OR (cua viet))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu viec cac lo va danh vai ((cua tre) OR (((cua triet) OR (cua viet))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu viec cac lo va danh vai ((cua tre) or (((cua triet) OR (cua viet))))*".
