title: ElasticSearch search for part of url
body: <p>I'm working with ElasticSearch 5 and can't find a solution for the following:
  I want to search for a string with slashes (part of a url) in a document. But it won't return matching documents.
  I've read something that strings with slashes are splitted by ES and that's not what I want for this field. I've tried to set "not_analyzed" on the field with a mapping, but I can't seem to get it to work somehow.</p>
