Scott Stults commented on SOLR-7495:
------------------------------------
[~rcmuir] added that line at the same time as the Insanity wrapper itself as
part of LUCENE-5666, but I'll take a crack at an explanation. There's only a
couple of cases outlined Insanity where we need to wrap the field, essentially
returning null instead of the docValues. When the collector returns null the
stored values of the field are used instead of docValues. Since stored values
are slower than docValues we only want to wrap the particular field type that's
problematic.
