title: facet serach results not showing the correct facet.field value
body: <p>I am trying to do a facet search on the following field:</p>
  
  <pre><code>&lt;field name="productTaxonomyName" type="text_en" indexed="true" stored="true" multiValued="false" /&gt;
  </code></pre>
  
  <p>the result for the facet search <code>select?q=gold&amp;rows=0&amp;wt=json&amp;indent=true&amp;facet=true&amp;facet.query=gold&amp;facet.field=productTaxonomyName</code> were:</p>
  
  <pre><code>facet_fields":{
    "productTaxonomyName":[
      "set",2018,
      "necklac",1937,
      "ear",1761,
      "ring",750,
      "pendant",524,
      "bracelet",348,
      "anklet",112,
  </code></pre>
  
  <p>The field values should be <code>necklace sets, necklaces, earrings, mangalsutras, rings, pendants, bracelets and anklets</code> instead of what is showing up in the results. </p>
