Zach Chen commented on LUCENE-9335:
-----------------------------------
bq. Actually you should be able to do it without modifying the benchmarking
code, by configuring your Competition object to not verify counts like that in
your localrun file: {{comp = competition.Competition(verifyCounts=False)}}
Ah I see. Thanks for the tip, will use that going forward!
bq. Indeed this indicates that the query returns different top hits with your
change. If the change was in the order of one ulp, then this could be due to
the fact that the sum might depend on the order in which clauses' scores are
summed up, but given the significant score difference, there must be a bigger
problem. Have you run tests with this change? This could help figure out where
the bug is.
Yes the *./gradlew check* was passing before, but I saw your comment in PR and
that calculation was indeed incorrect. Let me correct that and try again.

> 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.
