  A list of custom classifiers that the user has registered. By default, all built-in classifiers are included in a
  crawl, but these custom classifiers always override the default classifiers for a given classification.

  <b>NOTE:</b> This method appends the values to the existing list (if any). Use
  {@link #setClassifiers(java.util.Collection)} or {@link #withClassifiers(java.util.Collection)} if you want to
