David Smiley commented on SOLR-10321:
-------------------------------------
Looking back at this... I think I'm inclined to just drop the empty snippet
arrays. It wasn't and still won't be known if the document has a field value
just by looking at the highlighting output, but it's better than needless empty
output.
I filed a LUCENE side issue for the UH to address this, but I'd rather wait to
address it before a real user comes along instead of just a hypothetical need.
