Web search engines are now using tens of thousands of index servers that consume huge
amount of power. In this paper, we investigate FPGAs as the implementation platform for
power efficient index serving. We propose the architecture of an FPGA-based inverted index
search engine, as well as implementations of essential components, including decoder,
matcher and ranker. We successfully boot up the FPGA-based search engine and run
experiments on real-world data from a commercial search engine. The targeted FPGA …

Web search engines are now using tens of thousands of index servers that consume huge amount of power. In this paper, we investigate FPGAs as the implementation platform for power efficient index serving. We propose the architecture of an FPGA-based inverted index search engine, as well as implementations of essential components, including decoder, matcher and ranker. We successfully boot up the FPGA-based search engine and run experiments on real-world data from a commercial search engine. The targeted FPGA-based hardware index server could achieve up to 19.52X power efficiency and 7.17X price efficiency over an Intel Xeon server with highly optimized software. This is the first complete work using FPGAs to implement query processing for Web search engines.
