  // The 8.x-3.x version of Search API Solr behaves differently from 7.x-1.x.
  // Notably, it uses Hungarian notation for fulltext fields, such that
  // "tm_rendered_item" is indexed as "tm_X3b_en_rendered_item". We rely on consistent
  // field naming, so have to coerce that field and the "content" field, which
  // are used by the schema from Drupal 7.

      // default language, and Drupal 8 is language-sensitive. So we find items
      // that are named 'tm_*_LANGCODE_rendered_item' and use those.
