We have thousands of courses. Browsing for courses can be very difficult even with the categories and folder structures. There are only so many folder pathways we can create before those become overwhelming too. Learners have to click through multiple folders only to realize the content they are looking for is not there.
We'd like learners to have the ability to search within a folder (category/subcategory) and not have to search the whole category. We'd also like there to be search filters within those folders. For example: filter by language, filter by course level (introductory, beginner, etc.), filter by keyword, and filter by tags.
Unless a learner already knows exactly what course they're looking for, it's almost impossible to browse through the hundreds of courses we have in some categories to find something they're interested in.
