Well, that is the problem I am facing. Just checking if there is a way to
compute the diff from 18th for the 19th.
One option is:
Get all the facets for 19th.
Get all facets for 18th.
Do a diff and Eliminate intersection.

But this isn't optimal as the number of facets returned but solr query can
be huge.

Any other way to get around with? Any tool that solr provides?
