: Currently all Javadoc links seem to wind up pointing at the api-4_0_0-ALPHA versions - is that expected?
yes. /solr/api has always pointed at the javadocs for the most recent release of solr. All that's changed now is that we host multiple copies of hte javadocs (just like Lucene-Core has for a long time) and the canonical URLs make it clear which version you are looking at. there's an open Jira to make a landing page listing all the versions that i'm going to try to get to later today, but you can still find the 3.6 javadocs here... http://lucene.apache.org/solr/api-3_6_0/ : E.g. do a Google search on StreamingUpdateSolrServer. First hit is for "StreamingUpdateSolrServer (Solr 3.6.0 API)" : : Follow that link, and you get a 404 for page : http://lucene.apache.org/solr/api-4_0_0-ALPHA/org/apache/solr/client/solrj/impl/StreamingUpdateSolrServer.html that's to be expected: 1) google hasn't recrawled yet so it doesn't know about the new versions in general 2) that class was removed in 4.0 -Hoss
