title: Solr and TYPO3 faceting
body: <p>I've created a field called &quot;international&quot; in my TYPO3 project. This field is a checkbox and is displayed on my backend with an associated label.</p>
  <pre class="lang-php prettyprint-override"><code>'international' =&gt; [
      'exclude' =&gt; FALSE,
      'label' =&gt; 'LLL:EXT:projects/Resources/Private/Language/locallang_db.xlf:tx_projects_domain_model_requestprojects.international',
      'config' =&gt; [
          'type' =&gt; 'check',
          'items' =&gt; [
              // label, value
              ['LLL:EXT:projects/Resources/Private/Language/locallang_db.xlf:tx_projects_domain_model_requestprojects.international.items.1', 1],
          ],
      ]
  ],
  </code></pre>
  <p>If I go to my frontend, the faceting is indeed showing the field as link to filter my content thanks to this :</p>
  <pre><code>fieldRenderingInstructions {
  
      international =&lt; plugin.tx_solr.search.faceting.facets.international.renderingInstruction
      international.field = international_intS
  }
  
  faceting {
    facets.international {
      label.data = LLL:EXT:skin/Resources/Private/Language/locallang.xlf:tx_projects_domain_model_requestprojects.international
      field = international_intS
      renderingInstruction = TEXT
      renderingInstruction {
          field = optionValue
          wrap = {LLL:EXT:projects/Resources/Private/Language/locallang_db.xlf:tx_projects_domain_model_requestprojects.international.items.|}
          insertData = 1
      }
    }
  }
  </code></pre>
  <p>Starting with this, I have 2 questions:</p>
  <ol>
  <li>Why does my content which have the field &quot;international&quot; not selected are triggering an &quot;extra faceting&quot; this the name of my root page?</li>
  </ol>
  <p>If I have 2 &quot;international&quot; and 3 &quot;international&quot; not checked, my facets returns &quot;international (2)&quot; and &quot;root page (3)&quot; ? (the 3 have an empty value)</p>
  <ol start="2">
  <li>How can I hide this facet, but keep getting the value that was set to my content ?</li>
  </ol>
  <p>I need to hide this facet on front (but probably I will have to fix the &quot;bug&quot; from 1), but keep the given value.</p>
