The PageFly Landing Page Builder app is an advanced tool that allows creating sale-boosting pages. The Smart Search & Filter app is integrated with it, and you don't need to make any adjustments. You can see that the integration is enabled in the Smart Search & Filter control panel > Integrations section > Storefront part:

Within the integration:

  1. The Smart Search & Filter app builds into the Search Form element of a PageFly app's page. So your customers can use all advantages of Smart Search on the pages by PageFly.
  2. The Smart Search & Filter app indexes pages published by PageFly: Regular Pages, Blog Post Pages. So your customers can find these pages in the search results. 
    Note
After adding, editing, or deleting pages, you need to start the indexation manually. To do that, click the Force re-indexation button in the Smart Search & Filter control panel > Dashboard section.
