This simply shouldn't be the case if by "duplicate" you mean it has
the same id (i.e. the field defined as the uniqueKey in schema.xml).
If you do have docs in different shards with the same ID, then
something is very strange about your setup.

What version of Solr BTW?

Assuming you mean "same content but different IDs" then you can delete
by ID either through SolrJ or on the URL
.../collection/update?commit=3Dtrue&stream.body=3D<delete><id>idhere</id></=
delete>

Best,
Erick
