Typical access points for Internet, intranet and wireless traffic are described. Traffic flow through an Internet Service Provider is used as a preferred embodiment to exemplify the data traffic used as the input source in the invention. The invention teaches how proper privacy and content filters can be applied to the traffic source. The filtered data stream from the traffic flow can be used to improve the quality of existing searching and alerting services. The invention also teaches how a cache can be developed optimized for holding fresh searchable information captured in the traffic flow. It is further disclosed how the said cache can be converted to a searchable index and either separately or in cooperation with external search indexes be used as a basis for improved search services. The invention also discloses how the traffic flow can be analyzed in order to derive added information for measuring document relevance, access similarity between documents, personalized ranking of search results, and regional differences in document accesses.
