• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sai) OR (tu san)) ky nang xa hoi. hieu van ((nam xuc) or (nam xua)) va thanh vien cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sai) OR (tu san)) ky nang xa hoi. hieu van ((nam xuc) OR (nam xua)) va thanh vien cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sai) OR (tu san)) ky nang xa hoi. hieu van ((nam xuc) or (nam xua)) va thanh vien cua viet".
• Adding a wildcard symbol may retrieve word variants: ((tu sai) OR (tu san)) ky nang xa hoi. hieu van ((nam xuc) or (nam xua)) va thanh vien cua viet*.
