摘要
A query server system (figure 2) that processes queries of data and information stored in one or more data sources (130). The query server system includes a query server (100, 120, 121), a query source interface connected to the query server for receiving queries, data and information source (130) connected to the query server and an external index associated with said data and information source. The query server receives a query through the query source interface, processes the query using the external index (120) to generate result-set pointers, sending the result-set pointers to the data source, receiving result set data from said data source and providing result-set data via the query source interface.
