jpountz opened a new issue, #12644:
URL: https://github.com/apache/lucene/issues/12644
### Description
Counts on disjunctions could be optimized in the following case:
- 2 clauses
- both clauses are term queries
- there are no deletes
Then we could compute the count as `count(clause1) + count(clause2) -
count(clause1 AND clause2)` which almost certainly runs faster.
If we do that we'll probably want to update nightly benchmarks to either
have deletes or add tasks on disjunctions of 3 terms or more to retain coverage
on actual disjunction counts.
