Matt - Those params (query, facets, and velocity) are defined in params.json as Erick mentioned. See here:
https://github.com/apache/lucene-solr/blob/master/solr/server/solr/configsets/data_driven_schema_configs/conf/params.json <https://github.com/apache/lucene-solr/blob/master/solr/server/solr/configsets/data_driven_schema_configs/conf/params.json> I did a bit explaining of this here - https://lucidworks.com/blog/2015/12/08/browse-new-improved-solr-5/ <https://lucidworks.com/blog/2015/12/08/browse-new-improved-solr-5/> Hope that helps.
