Using filtering, Guided Navigation, and Search

The following examples explain how search filtering and Guided Navigation work in Big Data Discovery.

The Catalog, Explore, Transform, and Discover areas in Studio make use of powerful search and data-driven Guided Navigation capabilities of Big Data Discovery.

In the Catalog, refinements are always available on the left sidebar.

For data sets in projects, you can expand or collapse the sidebar using the funnel icon. If you expand it, it looks like this:

Using refinements, you can filter on attributes or on available metadata such as creation date. In the Catalog, this also includes any tags that users add to projects or data sets.

Selected refinements represent applied filters. They show up as breadcrumbs at the top of your screen. Here is an example of a selected refinement from the attribute complaint = BRAKE FAILURE. Notice that applying the refinement reduces the number of matching records to only 1.2k of the 37.8k total records in the data set.

Attribute filters apply across all parts of BDD. If you highlight or exclude attributes, you project reflects these selections when you move from the Catalog to Explore to Transform and back. For example, if you select all numeric attributes in a data set in Explore, and then switch to Transform, Transform is filtered by all numeric attributes.

You can also search data sets at any stage in your workflow using the search box:

In addition to searching across project and data set content, keyword search results from the Catalog also include any notes that users add to describe projects or data sets.

Like refinement filters, keyword search filters apply across both Explore and Transform if you switch between pages.
