Abstract: The present invention relates to a method for searching for and selecting Web pages in conjunction with a search equation, including a step of determining, through at least one search engine, an initial set of Web pages, and a step of determining a first set of Web sites including sites corresponding to the Web pages of the initial set. Sites are linked by intersite links, and one site is linked to another site by an intersite link when there is one or more hypertext links between Web pages of the two sites considered. At least one filtering operation based on the intersite links is provided, applied to the first set of sites and eliminates sites linked to the other sites of the first set of sites by less than NL intersite links. N is a filter parameter at least equal to 1 in order to obtain at least a first reduced set of sites comprising at least one core of rank NL of the first set of sites.
