czjxy881 opened a new pull request, #16547:
URL: https://github.com/apache/lucene/pull/16547

   ### Description
   
   Prevent `RangeBulkScorer` from passing an empty range to 
`LeafCollector.collectRange` when it receives an empty scoring window. 
`ReqExclBulkScorer` uses such windows to obtain the next-match estimate, while 
`LeafCollector.collectRange` requires `max` to be greater than `min`.
   
   Add regression coverage for an empty scoring window inside the scorer's 
query interval.
   
   Closes #16546.
   
   ### Tests
   
   - Confirmed the new test fails before the production change.
   - `./gradlew :lucene:core:test --tests 
org.apache.lucene.document.TestRangeFilteredBulkScorer --tests 
org.apache.lucene.search.TestReqExclBulkScorer`
   - `./gradlew tidy`
   - `./gradlew :lucene:core:check` (`8677` tests passed, `320` skipped)
