David Smiley created LUCENE-7875:
------------------------------------
Summary: Rename or move most of MultiFields
Key: LUCENE-7875
URL: https://issues.apache.org/jira/browse/LUCENE-7875
Project: Lucene - Core
Issue Type: Improvement
Reporter: David Smiley
MultiFields.java has a bunch of static methods that provide a single
LeafReader's view over a bunch of things.
These could perhaps go to ReaderUtil:
* {{Bits getLiveDocs(IndexReader reader)}}
* {{FieldInfos getMergedFieldInfos(IndexReader reader)}} (removing "Merged" in
its name which seems inconsistent, or replace with "Multi")
These could perhaps go to MultiTerms:
* {{Collection<String> getIndexedFields(IndexReader reader)}}
* {{Terms getTerms(IndexReader r, String field)}}
* {{PostingsEnum getTermDocsEnum(IndexReader r, String field, BytesRef term)}}
Finally, the MultiFields instance itself, implementing {{Fields}} along with
the static utility method {{Fields getFields(IndexReader reader)}} could
perhaps remain until we can finally remove it (or move to a test classpath or
something) when there is no more purpose for Fields.java.
