> Lucene often gets benchmarked against other engines, e.g. against Tantivy and PISA at [https://tantivy-search.github.io/bench/] or against research prototypes in Table 1 of [https://cs.uwaterloo.ca/~jimmylin/publications/Grand_etal_ECIR2020_preprint.pdf]. Given that top-level disjunctions of term queries are commonly used for benchmarking, it would be nice to optimize this case a bit more, I suspect that we could make fewer per-document decisions by implementing a BulkScorer instead of a Scorer.
