Views Page Not Appearing in Search Results
To answer the first of two questions: Yes, this is the expected behavior. Views pages are not indexed by Drupal core search.

For the second, Drupal core search is limited. More is possible by using Apache Solr search integration. 
According to https://www.drupal.org/node/2570521, https://www.drupal.org/project/apachesolr_nan is an example of a module that may do what you need. But you would need access to a Solr server.
