Answer 1

Gloopy's answer is spot on. I implemented it in my site but I was getting an error,

'input' is undefined

This occurred because I was sometimes looping over nothing. I fixed this by adding a conditional to return the empty out array if input was undefined.

var myApp = angular.module('myApp', []);
myApp.filter('regex', function() {
  return function(input, field, regex) {
      var patt = new RegExp(regex);      
      var out = [];

      if(input === undefined) {
          return out;
      }

      for (var i = 0; i < input.length; i++){
          if(patt.test(input[i][field]))
              out.push(input[i]);
      }      
    return out;
  };
});

Hopefully this will help someone who might be having the same problem
