• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky nang xa hoi. hieu va tham ((xuc va) OR (((tuc va) OR (thuc dan)))) hanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang xa hoi. hieu va tham ((xuc va) OR (((tuc va) OR (thuc dan)))) hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang xa hoi. hieu va tham ((xuc va) OR (((tuc va) OR (thuc dan)))) hanh vi cua te*.
