Hello, A related question on this topic. How do I programmatically find the total number of documents across many shards ? For EmbeddedSolrServer, I use the following command to get the total count : solrSearcher.getStatistics().get("numDocs")With distributed search, how do i get the count of all records in all shards. Apart from doing a *:* query, is there a way to get the total count ? I am not able to use the same command above because, I am not able to get a handle to the SolrIndexSearcher object with distributed search. The conf and data directories of my index reside directly under a folder called solr (no core) under the weblogic domain directly. I dont have a SolrCore object. With EmbeddedSolrServer, I used to get the SolrIndexSearcher object using the following call : solrSearcher = (SolrIndexSearcher)SolrCoreObject.getSearcher().get();
A *:* query with rows=0 is how I get a total document count. The program that does this most often is Perl using LWP, but I'm pretty sure I could do the same thing with the Commons server in SolrJ. I've never used the embedded server. I do not specify the shards parameter on my requests, I query a special core that has the shards parameter in solrconfig.xml.
Thanks, Shawn
