URL retrieval method and system

摘要

In a URL retrieval system and a URL retrieval method, a user is not required to assume a keyword for information to be accessed and in which even when many URL are obtained through a search, the user need not select desired URL therefrom. A proxy search server (200) creates a search expression using information from a user terminal (100). A search engine server (300) extracts URL according to the search expression from the search server (200). If the number of the extracted URL exceeds a predetermined value, the search engine server (300) sends information indicating for each URL a hierarchic level to which the URL belongs via the proxy engine server to the terminal for user selection. From the extracted URL, the engine server (300) obtains URL belonging to a hierarchic level selected by the user. If the number of the URL does not exceed a predetermined value, the engine server (300) sends the URL as a retrieval result via the proxy engine server (200) to the user terminal (100) for user selection.
