Exploring parameters in the model

As with all the elements in LookML, Explores in the model files have their own parameters to describe, filter, join data, define cache rules, and so on. Some of them are quite similar to other elements’ parameters and are used to describe and organize the data – tags, description, group_label, hidden, label, view_label, view_name, from, and fields. The from parameter in an Explore specifies the view that provides the fields for it (explore: explore_name {from: view_name}). If it is omitted, Looker will assume that the underlying view has the same name as the Explore. The fields parameter lets you control which fields from an Explore are visible in the Explore user interface.

There are some parameters in Explores that help you to reuse existing elements, such as extends (to reuse and complete the existing Explore) and persist_with (to reuse the existing datagroup caching policy).

In this section, we will explore the most commonly...
