Sort of… if you indexed the full value of the field (and you’re looking for
truly exact matches) as a string field type you could facet on that field with
facet.mincount=2 and the facets returned would be the ones with duplicate
values. You’d have to drill down on each of the facets returned to find the
actual docs.
