wei wang updated SOLR-17310:
----------------------------
Description:
Lucene's IndexWriterConfig provides the option to sort leaf readers when a
custom LeafSorter is provided.
[https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/index/IndexWriterConfig.java#L494]
The functionality is currently not directly exposed in Solr. One use case is in
early termination, we would like to search the more recent updated segments
first. The SegmentTimeLeafSorter sorts the LeafReaders by time stamp, so that
recent NRT segments can be traversed first. The feature is enabled by adding
the *segmentSort* config in solrconfig.xml. Without the config, no sorting is
applied by default.
