Adrien Grand commented on LUCENE-4858:
--------------------------------------

bq. The reason I did that is in case someone will want to sort by a stored field and numeric field which have same names.

A Sorter which sorts by stored field values would indeed need to add more information to its ID (at least to say that it is a stored field).

bq. "numericdv_field" is really unique, as you cannot have two numeric DV fields with the same name, but different meaning.

Since doc values types are exclusive, could we then just say that these are doc values without mentioning the type? I think this would help keep up with doc values types evolutions (for example there used to be BYTES_FIXED_SORTED and BYTES_VAR_SORTED which have been merged into SORTED) and/or additions (SORTED_SET). I would also prefer having something even more human-readable (like "DocValues(fieldName=$fieldName,order=asc|desc)"?).

> When an index is sorted per-segment, queries that sort according to the index sort order could be early terminated.
