Adrien Grand created LUCENE-5782:
------------------------------------
Summary: Improve OrdinalMap compression by sorting the supplied
terms enums
Key: LUCENE-5782
URL: https://issues.apache.org/jira/browse/LUCENE-5782
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
Fix For: 5.0, 4.10
As mentionned in LUCENE-5780, OrdinalMaps might have much better compression
when the terms enums are supplied sorted by descending cardinality. When it is
not the case, we could sort the enums and re-map segment indices on top of it.
