Replace docBase with actual docId in MaxScoreAccumulator (#13777) We have been encoding docBase and the score in MaxScoreAccumulator#accumulate. That makes the assumption that segments are going to be processed in doc order and implements global max score accounting across segments searched concurrently. With the introduction of intra-segment concurrency, the same segment may be seen multiple times, once per segment partition. Partitions are all going to have the same docBase, hence you may end up with topN results with higher docIds than expected, because the search early terminates before docs with same score and lower doc ids are seen. This commit encodes the docId in the accumulator in place of the docBase to resolve the described issue.
Apache Lucene is a high-performance, full-featured text search engine library written in Java.
