Both Archives and WPPITVGuide provide a powerful form of seach by utilizing Filters. Filters are grouped into four categories and make it easy to search selectively by either individual categories or multiple categories. Simply click on a category like "Topics" and you will be able to see every article or video that covers that Topic. You'll also be able to click on another category, or all categories to help refine the search even further. Proceed with your selection or start a new search by clicking on "Remove Filters".
