title: regex: match any word with numbers
body: <p>I checked on stackoverflow already but didn't find a solution I could use.
  I need a regular expression to match any word (by word I mean anything between full spaces) that contains numbers. It can be alphanumeric <strong>AB12354KFJKL</strong>, or dates <strong>11/01/2014</strong>, or numbers with hyphens in the middle, <strong>123-489-568</strong>, or just plain normal numbers <strong>123456789</strong> - but it <strong>can't</strong> match anything without numbers.
  Thanks,</p>
  
  <p>Better example of what I want (in bold) in a sample text:</p>
  
  <p><strong>ABC1</strong> ABC <strong>23-4787</strong> ABCD <strong>4578</strong> ABCD <strong>11/01/2014</strong> ABREKF</p>
