title: Regex match two words in a string
body: <p>I'm trying to match (look for) two words in a string which is as follows:</p>
  
  <pre><code>Mac OS X/10.11.5 (15F34); ExchangeWebServices/6.0 (243);
  </code></pre>
  
  <p>I want to match (true) if we see "<code>Mac</code>" AND "<code>ExchangeWebServices</code>" but the characters between the two words would be unknown/random. Can someone help me with the regex syntax?</p>
  
  <p>Thanks!</p>
