/**
* Routes the incoming nodes (not ACLs!) on the last registered indexing shard (LRIS).
* Routes the incoming nodes (not ACLs!) on the shard explicitly indicated in {@link Node#getExplicitShardId()} method.
* The access control information is duplicated in each shard.
*
* <p><br/>
* WARNING: This is an experimental feature that is subject to change.
* The current known issues are:
*
* <ul>
* <li>Incompatibility with the "Purge" action on the Alfresco Admin Console</li>
* <li>Incompatibility with the "Purge on Startup" option on the Alfresco Admin Console</li>
* </ul>
*
* As a result, when this router is used and the purge action is invoked you may experience a wrong shard subscription
* registration order. That would cause a wrong distribution of the indexed data across the cluster.
*
* Note the "Purge on restart" option on the Admin Console is checked by default, so before building a
* Solr cluster which uses this router, please make sure the check has been disabled.
*
* </b><br/><br/>
* </p>
*
* Specifically, until the whole feature will be officially released, the LRIS document routing feature is not compatible
* with the "Purge" action on the Alfresco Admin Console.
* Note that at time of writing, the "Purge on startup" option in the Admin Console is enabled by default so prior to
* build your search cluster, you have to make sure that option is unchecked.
