Hi. I have encountered a similar situation when I tested solr merge index . ( http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201403.mbox/%3CCAMrn6cOVWohxooRzZ8NmwYQUda2GW+gYD+edvC_b_kGT=f4...@mail.gmail.com%3E )
I have had duplicates. But the duplicates are gone when I post same data for indexing. I think this was done in order to prevent data loss while merging index. 2014-04-07 23:04 GMT+03:00 Erick Erickson <erickerick...@gmail.com>: > Oh my yes!
