I have crawled some web pages and indexed them at my SolrCloud(Solr 4.2.1). However before I index them there was already some indexes. I can calculate the difference between current and previous document count. However it doesn't mean that I have indexed that count of documents. Because urls of websites are unique ids at my system. So it means that some of documents updated and they did not increased document count.
My question is that: How can I learn the total count of how many documents indexed and how many documents updated?
