title: How to override search in Magento?
body: <p>My user should be able to use the search box to search by some attribute (numeric) it works.</p>
  
  <p>But I'd like to my customer to be able to search using separator.</p>
  
  <p>Example:</p>
  
  <p>search by : 12345678 = works great</p>
  
  <p>search by : 12-34-56-78 = doesn't work</p>

  <p>Thank you</p>
