Search overview
On the Cloudera Data Catalog Search page, select a data lake and enter a search string in the search box to view all the assets with details that contain the search string.
When you enter the search terms in Search, you are looking up names, types, descriptions, and other metadata collected by Cloudera Data Catalog. The search index includes metadata (not data) about your environment and cluster data assets and operations. You can make the search more powerful by associating your own information (business metadata) to the stored assets.
