title: Regex rule to exclude url with specific word
body: <p>When I search for " abc 920 def" on my site, the domain fires:</p>
  
  <pre><code>http://www.domain.com/?s=abc+920+def
  </code></pre>
  
  <p>Then, this redirection rule:</p>
  
  <pre><code>​/?(.*)=(.*)920(.*)
  </code></pre>
  
  <p>will redirect it to a category:   <code>domain.com/all-things-920/</code></p>
  
  <p>The problem now is that I have some other pages that generate random numbers for receipt pages, such as: </p>
  
  <pre><code>/store/receipt/?ouid=0955a8980823k920
  </code></pre>
  
  <p>Because that url contains <code>920</code>, it will redirect it to the category <code>domain.com/all-things-920/</code>  which I don't want.</p>
  
  <p>I tried playing with some regex combinations without any luck.
  Is there a way to exclude the regex rule if the url contains  <code>ouid</code> in it?</p>
  
  <p>I tried:  <code>/?(?!ouid)(.*)=(.*)920(.*)</code>   without luck.</p>
  
  <p>When I use the rule  <code>/?s=(.*)920(.*)</code>,  it will place <code>/?/</code>  in the middle of the url path. For example  <code>domain.com/?/all-things-920/</code></p>
