1. A web site search and selection method comprising: responding to a search query by assigning a relevance score to each page of web sites containing a number of pages addressed by a search engine, wherein, for each web site addressed by the search engine, said method comprises the following operations: adding together relevance scores of individual pages identified by the search engine, weighting said relevance scores by a correction factor indicative at least of the number of pages of the web site, and obtaining, in response to the search query, an overall web site relevance index for the web sites addressed by the search engine wherein said web site relevance index (SRI) is determined by a formula: 
 SRI=Σ 1 [rl i 100+NormSite (web site pages)] where rl i indicates the relevance score of the i th page found and NormSite (web site pages) is a hyperbolic correction factor calculated by NormSite (web site pages)=k*[(YI/p)+Δy], where: p indicates the number of pages in the web site; YI indicates a coordinate on the y-axis at the x-axis point I in a plot of relevance (y-axis) against page number (x-axis); k is a correction factor; and Δy indicates a horizontal asymptote above which a hyperbola is positioned; at least one of said operations being implemented on a computer having a processor and a memory coupled to said processor.
