• Performing a fuzzy search may retrieve terms with similar spellings: ((so sanh) OR (do sanh)) ky nang x hoi. hieu van ((tham xuc) or (tham nuoc)) va danh van cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sanh) OR (do sanh)) ky nang x hoi. hieu van ((tham xuc) OR (tham nuoc)) va danh van cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sanh) OR (do sanh)) ky nang x hoi. hieu van ((tham xuc) or (tham nuoc)) va danh van cau tren".
• Adding a wildcard symbol may retrieve word variants: ((so sanh) OR (do sanh)) ky nang x hoi. hieu van ((tham xuc) or (tham nuoc)) va danh van cau tren*.
