US Patent 7181444 System and process for searching a network

A system for searching a network for network based content related to a search query, such as multimedia and streaming media, includes an adapter for formatting the search query, a first database containing previous search results and a second database for storing currently returnable metadata, a search processor, and at least one search engine kernel comprising a search engine inherent database. The search engine coordinates searching of the first database and the second database, and and provides the formatted search query to the search engine kernel. The search processor also provides and receives search results to and from the first database and the second database, and provides search results to the adapter. The system stores a predetermined amount of previous search results in the first database, such that search results for a current search are retrieved from the database, avoiding a search through search engine kernel, comprising searchable metadata.
