add_filter posts_results

I want to filter the results of a search. I need to examine the result set and remove some posts based on the existence of others. I beleive that the filter posts_results is the correct filter to use but when I dump the $posts array I only get one object. That happens to be the only embedded video on the site and not a post.

I changed the filter to return an empty array but it doesn’t change the results on the search page. This is from the codex example. I stopped at the point where the ‘error_log(print_r($posts, true));’ returns just one result where the search page displays several results.

function preferCustomContentFilter($posts) {
  $filtered_posts = array();
  error_log(print_r($posts, true));
  foreach ($posts as $post) {
error_log("HERE");
    if (false === strpos($post->post_title, 'selfie')) {
    // safe to add non-selfie title post to array
    $filtered_posts[] = $post;
    }
  }
  //return $filtered_posts ;

  // try to affect the search/results page
  return array();
}
add_filter('posts_results', 'preferCustomContentFilter');
