MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test plan:
  - Use Elasticsearch 6 (you'll need Bug 18969),
  - create a biblio (#1) with "Dillinger Girl" in author and what you
    want in title,
  - create another biblio (#2) with the word "girl" in the title and
    "Dillinger Escaplan" as author
  - reindex
  - search * and refine on "Dillinger Girl"
  - Ko => Biblio #1 and #2 appear
  - Apply this patch,
  - search * and refine on "Dillinger Girl"
  - Ok => anly biblio #1 appears
  - use Elasticsearch 5 again
  - check for no search regression
