Description

MultiFields.java has a bunch of static methods that provide a single LeafReader's view over a bunch of things.

This goes to MultiBits (which will become public):

• Bits getLiveDocs(IndexReader reader)

These go to FieldInfos:

• FieldInfos getMergedFieldInfos(IndexReader reader)
• Collection<String> getIndexedFields(IndexReader reader)

These go to MultiTerms:

• Terms getTerms(IndexReader r, String field)
• PostingsEnum getTermPostingsEnum(IndexReader r, String field, BytesRef term) which is renamed a little
