You can find any resource in Collibra, such as assets, communities, domains, users, and user groups, using the quick search box on the main toolbar. When you search for something using the quick search box, you are taken to the Search page, where you can refine the search results as needed.
In the latest UI, depending on your permission, the search page includes the Data Marketplace tab, which allows you to search for specific asset types, such as data sets, reports, and tables.
