Running 4.8.1. I am experiencing the same problem where I get duplicates on index update despite using overwrite=true when adding existing documents. My duplicate ratio is a lot higher with maybe 25 - 50% of records having duplicates (and as the index continues to run the duplicates increase from 2 to 3,4,5 etc).
<field name="key" type="string" indexed="true" stored="true" required="true"/> and <uniqueKey>key</uniqueKey> are set in the schema.xml but along with overwrite="true" this still doesn't guarantee uniqueness.
