This helps you understand which filters are used the most and optimize your content for better user experience.

= Search Feature with Voice Search =

CAF Pro includes an advanced **search filter** that allows visitors to quickly find content by typing keywords or using **voice search [Demo] (https://caf.trustyplugins.com/layouts/caf-full-width-timeline/)**. This makes searching faster and more convenient, especially on mobile devices.

CAF Pro provides flexible pagination options to improve content browsing. You can display results using **Load More buttons, AJAX pagination or traditional navigation**, allowing visitors to explore more content without refreshing the page.
