Summary: Indexsort is not correct（java.lang.RuntimeException:
segment has indexSort=<sortednumeric: "time">!
missingValue=-9223372036854775808 selector=MAX type=LONG but docID=136 sorts

Key: LUCENE-10210
URL: https://issues.apache.org/jira/browse/LUCENE-10210
Project: Lucene - Core
Issue Type: Bug
Components: core/index
Affects Versions: 7.2.1
Reporter: xunjian
Sequence of test:
# create an index with indexsort(final SortField sortField = new
SortedNumericSortField("time", SortField.Type.LONG, true,
SortedNumericSelector.Type.MAX);sortField.setMissingValue(Long.MIN_VALUE);Sort
sort = new Sort(sortField);)
# index 200 docs （time is null）
# index 600 docs (time is not null )
# index 100 docs (time is null)
# conmit and flush
# search
** final int numHits = 3;
final SortField sortField = new SortedNumericSortField("time",
SortField.Type.LONG, true, SortedNumericSelector.Type.MAX);
sortField.setMissingValue(Long.MIN_VALUE);
final TopFieldCollector collector = TopFieldCollector.create(new
Sort(sortField), numHits, null, true, false, false, false);
final Query query = new MatchAllDocsQuery();
searcher.search(query, collector);
TopDocs td = collector.topDocs();
# assert
** long time = ((FieldDoc) td.scoreDocs[0]).fields[0]
** System.out.println(time);
problem:
# the time is not what I expected
# when close the index reader, I got the error: java.lang.RuntimeException:
segment has indexSort=<sortednumeric: "time">!
missingValue=-9223372036854775808 selector=MAX type=LONG but docID=136 sorts
after docID=137.
