It's a silly thing, but to confirm the direction that Erick is suggesting :
How many rows in the DB ?
If updates are happening on Solr ( causing the deletes), I would expect a
greater number of documents in the DB than in the Solr index.
Is the DB primary key ( if any) the same of the uniqueKey field in Solr ?
