Interesting. I will definitely explore this. Just so I'm clear, we can sort on
docValues, but not filter? Is there any situation where external file fields
would work better than docValues?

Subject: RE: External file fields
: I did look into updatable docValues, but my understanding is that the
: field has to be non-indexed (indexed="false"). I need to be able to sort
: on these values. External field fields are sortable.
YOu can absolutely sort on a field that is docValues="true"
indexed="false" ... that is much more efficient then sorting on a field that is
docValues="false" index="true" -- in the later case solr has to build a
fieldcache (aka: run-time-mock-docvalues) from the indexed values the first
time you try to sort on the field after a searcher is opened
