Shai Erera commented on LUCENE-4765:
------------------------------------

I briefly looked at the patch, looks good. Perhaps instead of returning an iterator, we should return an IntsRef? While optimizing facets code, Mike and I observed the "iterator-based API" is not so good for "hot code", and e.g. if we'll want to use this for faceting, a bulk-API would be better I think.

Same question for indexing -- in facets, we get all the ordinals at once, so is it possible to have a field which takes a list of ordinals instead of adding many instances of SortedSetDVField?

> The general idea is basically the docvalues parallel to FieldCache.getDocTermOrds/UninvertedField
> Currently this stuff is used in e.g. grouping and join for multivalued fields, and in solr for faceting.
