Abstract: A social network searching system includes a user profile storage, a profile search engine and a linkage construction engine. The user profile storage stores user profiles. The profile search engine obtains a target member by searching the user profile storage based on a profile query from a query user. The linkage construction engine constructs a relationship linkage and extracting an optimal path from at least two paths from the query user to the target member according to a relationship linkage. A member searching and analyzing method of social network is also disclosed.
