title: how do I make a search box that accepts regular expression to search data?
body: <p>If the user enters " Mil* " then the search should return "Milk", "Milk Cake", "Milk sweet", "Milky bar chocolate"... 
  I'm trying to make a SAP UI5 Application, where the filter understands regular expression. Then the result is displayed in a table.</p>
  
  <pre><code> var oFilter = new sap.ui.model.Filter({
                          path     : "ProductName", 
                          operator : CustomFilterToAcceptRegEx,
                          value1   : "Milk"
                      });
  </code></pre>
  
  <p>I can't think of anyway to do this. Any advice would be helpful. 
  I'm totally new to javascript &amp; SAP UI5</p>
