Facet suggestions are not displayed out-of-the-box. A handle function should be implemented that directs the user to the correct page when the user selects these suggestions.

<script>
  window.addEventListener("twn.suggestions.ready", function () {
    window.tweakwiseSuggestions({
      //..
      
      facetFilters: {
        handle(event) {
          var suggestion = event.data;
          // Handle facet suggestion here...
        }
      }
    });
  });
</script>

Example: brand suggestion

<script>
  window.addEventListener("twn.suggestions.ready", function () {
    window.tweakwiseSuggestions({
      //..
      
      facetFilters: {
        handle: function (event) {
          const filterContext = event.data.navigationLink.context.facetFilters[0];
          if(filterContext.key == 'ae-brand'){
            const value = filterContext.values[0];
            let brandFixedForUrl = brand.replace(/['"]/g, '').replace(' ', '-').toLowerCase();
            window.location.href = `/brands/${brandFixedForUrl}`;
          }
          else {
            location.href = '/search#twn|?tn_q=' + e.data.match;
          }
        }
      }
      
    });
  });
</script>
