title: Regular expression in Search Sharepoint 2013
body: <p>I have problem to use regular expression at Sharepoint 2013 Search.
  I insert it into crawl rule and checked Use regular expression syntax for matching this rule.</p>
  
  <p>I valid my regex on page regex101 so I am sure at 100% it is right.</p>
  
  <pre><code>^(https?:\/\/)([\da-zA-z\.]+)\/([\da-zA-z]+)$
  </code></pre>
  
  <p>This is on the first place of craw rules and I select exclude, but pages are still searchable.
  What am I doing wrong?</p>
