You may have noticed some recent improvements to Community search!
When you search for information on the Community, you now have advanced filters available. Filter options include categories (CS, PX, Product News, etc.), post type (ideas, questions, articles), and tags.
Category specific search
When you search within a specific category, the dynamic search results (displayed directly under the search bar) are limited to that particular category. If you view the complete list of results, you will see potential matches from across the community, along with the advanced filter options.
