title: Word separators for Postgres full text search with Rails
body: <p>I'm using <a href="https://github.com/Casecommons/pg_search" rel="noreferrer">pg_search</a> for some text searching within my model. Among other attributes, I have an <code>url</code> field.</p>
  
  <p>Unfortuantelly Postgres doesn't seem to identify <code>/</code> and <code>.</code> as word separators, therefore I cannot search within the <code>url</code>.</p>
  
  <p>Example: searching for <code>test</code> in <a href="http://test.com" rel="noreferrer">http://test.com</a> yields no results.</p>
  
  <p>Is there a way to fix this problem, perhaps using another gem or some inline SQL ?</p>
