title: Looking for solr query which will include results with both missing field and the same field which has number within a given range
body: <p>Let's say I have the following data</p>
  
  <pre><code>{
   fruit: "Mango",
   cost : 2.00,
   variety : "alphanso",
  },
  {
   fruit : "apple",
   cost : 1.40,
   variety : "Gala"
  },
  {
   fruit : "apple",
   variety : "cosmic crisp",
  },
  {
  fruit : "apple",
  variety : "honey crisp",
  cost : 2.99
  }
  </code></pre>
  
  <p>I am looking for a search that returns apples with a cost between 1 and 2 and also returns the variety that doesn't have a cost field set.</p>
  
  <p>In this case, the result will contain "Gala" and "cosmic crisp"</p>
