Using the admin interface with solr will break with error 500 after login on the interface:

->response not set: array ( 0 => stdClass::_set_state(array( 'error' => stdClass::_set_state(array( 'metadata' => array ( 0 => 'error-class', 1 => 'org.apache.solr.common.SolrException', 2 => 'root-error-class', 3 => 'org.apache.solr.common.SolrException', ), 'msg' => 'can not sort on multivalued field: path_string_id', 'code' => 400, )), )), 1 => array ( 'defType' => 'edismax', 'q' => '

((document_type_id:"location") AND (meta_indexed_is_main_translation_b:"true") AND (location_id:"1" OR location_id:"2"))', 'sort' => 'path_string_id asc', 'start' => 0, 'rows' => 25, 'fl' => '*,score,[shard]', 'wt' => 'json', ), ) [in vendor/ezsystems/ezplatform-solr-search-engine/lib/Gateway/Native.php:466]

Creating the initial solr index with the console command works fine.

• create a new ezplatfom project on platform.sh
• configure using solr
• index the the content
• try to login on the admin interface
