A central index server 3 returns a list of files 6 and file locations which match the query results and are currently available. The client terminal 1 issuing the search can retrieve the file 6 from the search results by requesting it from one of the client terminals 1 specified in the search results.

Communication is established between a first client and a central index server in a fluid, de-centralized network. The central index server searches the memory of the first client for usable data files which lack authentication certificates issued by the central index server. A data-file identifier is generated for a first data file among the select files lacking authentication certificates within the first client. The data-file identifier is compared to a reliable identifier in a main data base of the central index server. The reliable identifier is indexed within the main data base against a first unique reference ID. If the data-file identifier matches the reliable identifier, a valid authentication certificate is issued to the first data file in the first client. An IP address of the first client is then referenced against the first unique reference ID within the main data base of the central index server. When file request is received from a second client for a file represented by the first unique reference ID, a connection is facilitated between the first client and the second client so that the authenticated first multimedia data file can be transferred from the first client to the second client. If the data-file identifier does not match the reliable identifier within the data base, no authentication certificate is issued, and the first data-file identifier is systematically compared against a remaining plurality of identifiers within the main data base of the central index server to determine its true identity.

A method and system for sharing full text index entries across application boundaries in which documents are obtained by a shared, platform level indexing service, and a determination is made as to whether the received documents are duplicates with regard to previously indexed documents. If a document is determined to be a duplicate, the index representation of the previously indexed copy of the document is modified to indicate that the document is also associated with another application or context. If a document is not a duplicate of a previously indexed document, the document is indexed to support future searches and/or other processing. The index representation of a document includes application category identifiers associating one or more applications or contexts with the document. When a document is indexed, one or more category identifiers are generated and stored in association with that document. The category identifiers for an indexed document may, for example, represent an application that received, stored, or otherwise processed that document. The application category identifiers enable category specific searching by applications sharing a common search index. A software category filter may be provided to process search results from the shared search index, so that only documents associated with certain categories are returned. Accordingly, one or more search categories may be determined for a given search query, based on an application generating the search query, or some other context information, and then used to filter the search results provided from the shared search index.
