title: How to filter by integer in solr keeping 0 in the set as last result?
body: <p>I want to filter my results in solr 6.4.1 by price while still keeping results in the set which have no price and pushing those with no pice to the end of the result list.</p>
  
  <p>dataset example: </p>
  
  <pre><code>item1 = $32
  item2 = $31
  item3 = 
  item4 = $33
  </code></pre>
  
  <p>Filter example query:</p>
  
  <pre><code>&lt;str&gt;{!tag=price}price:[1 TO *]&lt;/str&gt;
  </code></pre>
  
  <p>Result desired:</p>
  
  <pre><code>result4 = $31
  result4 = $32
  result4 = $33
  result4 =
  </code></pre>
  
  <p>Using 1 in the filter query will filter the empty result out of the set, pulling 0 as start it will return those items on top of the list.</p>
  
  <p>So the question is in other words is, how to sort by price with 0 as highest price result?</p>
