Tank you Emir. I tried this locally (changing schema, re-index all implace) and I wasn't able to sort on the doc value fields anymore (someone actually mentioned this before on that forum - https://lucene.472066.n3.nabble.com/DocValues-error-td4240116.html) with the next error "Error from server at http://10.150.197.29:8961/solr/accountmaster_shard1_replica1: unexpected docvalues type NONE for field 'key' (expected=SORTED). Re-index with correct docvalues type."
Also, having this great overhead you mention, is another reason not to reindex inplace. Thanks! -- Sent from: https://lucene.472066.n3.nabble.com/Solr-User-f472068.html
