LUCENE-10031: Speed up SortedDocIdMerger on low-cardinality sort fields. (#221) 
When sorting by low-cardinality fields, the same sub remains current for long
sequences of doc IDs. This speeds up SortedDocIdMerger a bit by extracting
the sub that leads iteration.

Introduction

Lucene is a Java full-text search engine. Lucene is not a complete application, but rather a code library and API that can easily be used to add search capabilities to applications.

Files in a binary distribution

Files are organized by module, for example in core/:

  • core/lucene-core-XX.jar: The compiled core Lucene library.

To review the documentation, read the main documentation page, located at: docs/index.html

To build Lucene or its documentation for a source distribution, see BUILD.md
