[jira] [Created] (LUCENE-9335) Add a bulk scorer for disjunctions that does dynamic pruning

Adrien Grand created LUCENE-9335:
------------------------------------

             Summary: Add a bulk scorer for disjunctions that does dynamic pruning
                 Key: LUCENE-9335
                 URL: https://issues.apache.org/jira/browse/LUCENE-9335
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand


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.
