What function does a Search Head fulfill in Splunk?

The Search Head in Splunk plays a crucial role by enabling users to conduct searches across indexed data and generate reports based on those search queries. It serves as the user interface for accessing Splunk, allowing users to submit search requests, visualize data through dashboards, and analyze results effectively. This interaction is key for data-driven decision-making, as it allows users to drill down into the data, filter results, and explore insights from various angles. Given its primary function, this characteristic differentiates it from other components in Splunk that focus on different functionalities like managing data storage or user activity.
