You got the point; I do have a the unique key defined, but for some reason, when i run the
delta-import; a new entry is created for the same record with a new unique key. Its almost
somehow it doesn't detect the existing record.

asking:  If you have a uniqueKey defined in your schema, then new documents with matching
values in the uniqueKey field will replace the existing documents.  Solr will delete the old
one before inserting the new one.
