I am a Drupal newbie and I am frustrated in my search for methods that allow admin searches of code in node content fields ie CSS classes. I'm baffled that there is not a built-in default way to help admins search content like this.
I have looked at many projects for Drupal 7 and Drupal 8 and only a few Drupal 7 modules looked like they could have helped. None of what I have read for Drupal 8 appears to offer code search.
The documentation I have read, and the module I found are the following.
- https://www.drupal.org/project/admin_views (D7)
- http://drupal.org/project/scanner (D7)
- https://www.drupal.org/project/find_content (D7)
