One of the unique capabilities of Discover is the ability to combine free text search with filtering based on structured data. To search all fields, enter a simple string in the query bar. To search particular fields and build more complex queries, use the Kibana Query language.
With Discover, you can quickly search and filter your data, get information about the structure of the fields, and display your findings in a visualization. You can also customize and save your searches and place them on a dashboard.
