for error
Unable to use updateLog: _version_field must exist in schema, using indexed="true" stored="true" and multiValued="false" (_version_ is not indexed

use the following link to resolve.
https://www.drupal.org/project/search_api_solr/issues/1676224

adding following line resolves the problem.
<field name="_version_" type="long" indexed="true" stored="true"/>
Following code can be used to alter the results thats coming from solr (while using search_api module)

 
function MODULE_search_api_results_alter(array &$results, SearchApiQueryInterface $query) {
  if (!empty($results['results'])) {
    foreach ($results['results'] as $id => $result) {
      if (!empty($result['fields']['search_api_viewed'])) {
        $results['results'][$id]['fields']['search_api_viewed'] = array(
          '#value' => $result['fields']['search_api_viewed'],
          '#sanitize_callback' => FALSE,
        );
      }
    }
  }
}

Code quality analysis of Drupal. Can I use Sonar?

Code smell: 10 Its possible that you can define following inheritance in Quality profile. For example: Sonarway=>Drupal Drupal uses PHPCodeSniffer (Drupal standards) or Coder to verify its coding standards. Both of them dont have integration with Sonar. 3.
