Towards feasibility and scalability of text search in peer-to-peer systems

— In this paper, we introduce a search engine, Dgoogle, designed for large scale P2P systems. Dgoogle is purely text-based, does not organize documents based on pre-defined keywords or based on their semantics. It is simple to implement and can tolerate variations in the wording of text queries. Compared to existing proposals, such as Inverted Indices, Dgoogle does not stress network bandwidth and offers an order of magnitude of savings in storage overhead and in the response time to user queries. Furthermore, Dgoogle’s performance is not affected by long queries or by processing popular query words. Simulation results validate the efficacy of our proposal.
