• Performing a fuzzy search may retrieve terms with similar spellings: ((tu san) OR (tu ban)) ky nang dai hoi. hieu sau ((phat xuc) or (phat xuat)) va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (tu ban)) ky nang dai hoi. hieu sau ((phat xuc) OR (phat xuat)) va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) OR (tu ban)) ky nang dai hoi. hieu sau ((phat xuc) or (phat xuat)) va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((tu san) OR (tu ban)) ky nang dai hoi. hieu sau ((phat xuc) or (phat xuat)) va hanh vi cua te*.
