A split-server architecture for processing a search query provided by a user, and identifying and retrieving documents from a database corresponding to the search query. A session server is provided for receiving the search query from the user. The session server has at least a first processor coupled to the user over a communications channel. A query server is coupled to the session server. The query server has at least a second processor coupled to a first database having records representative of the documents to be searched. The query server includes the ability to receive the search query from the session server, the ability to search the first database to identify documents responsive to the search query; and the ability to send search results information representative of the documents identified by the first database search from the query server to the session server. The session server includes the ability to send the search query to the query server, the ability to receive the search results information from the query server, the ability to send a search results list representative of the search results information across the communications channel to the user, the ability to receive a document retrieval request transmitted from the user over the communications channel, the ability to retrieve a document in response to the retrieval request and transmitting a file representative of the document to the user over the communications channel, and the ability to increment an accounting record on an accounting database coupled to the session server, the accounting record representing a number of retrievals of the document by the session server.

Architecture for processing search queries, retrieving documents

A method and apparatus for identifying textual documents and multi-media files corresponding to a search topic. A plurality of document records, each of which is representative of at least one textual document, are stored, and a plurality of multi-media records, each of which is representative of at least one of multi-media file, are also stored. The document records have text information fields associated therewith, each of the text information fields representing text from one of the plurality of textual documents. The multi-media records have multi-media information fields for representing only digital video or audio information and associated text fields, each of the associated text fields representing text associated with one of the multi-media information fields. A single search query corresponding to the search topic is received. The single search query is preferably in a natural language format. An index database is searched in accordance with the single search query to simultaneously identify document records and multi-media records related to the single search query. The index database has a plurality of search terms corresponding to terms represented by the text information fields and the associated text fields. The index database also includes a table for associating each of the document and multi-media records with one or more of the search terms. A search result list having entries representative of both textual documents and multi-media files related to the single search query is generated in accordance with the document records and the multi-media records identified by the index database search. Text corresponding to the search topic is retrieved by selecting entries from the search result list representing document records to be retrieved, and then retrieving text represented by the text information fields associated with the selected document records. Digital video or audio information corresponding to the search topic is retrieved by selecting entries from the search result list representing selected multi-media records to be retrieved, and then retrieving digital video or audio information represented by multi-media information fields associated with the selected multi-media records.
