WebAug 7, 2024 · We show these innovations yield a significant efficiency gain versus classic bit-sliced signatures and then compare BitFunnel with Partitioned Elias-Fano Indexes, MG4J, and Lucene. WebOct 22, 2016 · In this paper, we first compare performances of existing encoders in the space-time trade-off curve, then we present a faster algorithm to heuristically compute optimal partitions for the state-of-the-art Partitioned Elias-Fano index, taking account of compression time while maintaining the same approximation guarantees.
