Querying from the admin UI and not seeing anything in the server log sounds like browser caching. You can turn that off in solrconfig.xml. I could not duplicate what you're seeing with SolrJ. You didn't say what version of SolrJ, so I did this using 3.6.2 (same as your server version). I thought maybe if you had a query object that didn't have an actual query set, it might do what you're seeing, but that doesn't appear to be the case. I don't have a 3.6.2 server to test against, so I used my 3.5.0 and 4.2.1 servers.
