title: What is the Elasticsearch equivalent of a negated 'LIKE' or CONTAINS' statement?
body: <p>I would like to do the Elasticsearch equivalent of the following SQL statement:</p>
  
  <blockquote>
    <p>SELECT * FROM Users WHERE UserName NOT LIKE '%something%'</p>
  </blockquote>
  
  <p>I don't care about efficiency or scoring... This only gets executed on occasion. I am using request body syntax.</p>
