Hi Stefan, I am not aware of option to log only client side queries, but I think that you can find workaround with what you currently have. If you take a look at log lines for query that comes from the client and one that is result of querying shards, you will see differences - the most simple one, if you are not using solrj for querying, would be wt parameter: e.g. client request might have wt=json while shard requests would have wt=javabin. There are also parameters that are added by Solr for internal calls so just compare log lines you will find some discriminator in your version of Solr.
