As it is mentionned in the wiki that you referenced in the link , instanceDir parameter in the http request is a required parameter. config, schema & dataDir parameters are optional. (Default is to look for solrconfig.xml/schema.xml inside instanceDir. Default place to look for dataDir depends on solrconfig.xml.) Example of Create Request

    http://localhost:8983/solr/admin/cores?action=CREATE&name=coreX&instanceDir=path_to_instance_directory&
config=config_file_name.xml&schema=schema_file_name.xml&dataDir=data
