Which process handles fast search, filter, retrieval, and display of content metadata on the server?

The process that manages fast search, filter, retrieval, and display of content metadata on the server is the Search and Browse functionality. This component is essential for enhancing user experience by enabling efficient access to content within Tableau Server. It allows users to quickly find relevant reports, dashboards, and data sources by indexing and making metadata searchable.

This functionality is pivotal in environments where multiple users are accessing a vast array of content, as it streamlines the process of navigating through available resources. The Search and Browse feature essentially allows users to interact with the server's content in a way that prioritizes speed and relevance, ensuring that they can locate the information they need without unnecessary delays.

The other options focus on different aspects of Tableau’s functionality. For instance, Tableau Prep Flow Service relates to the data preparation process, functioning mainly to manage the execution of workflows that prepare data for analysis. VizQL Server is concerned with executing queries and rendering visualizations rather than indexing content metadata. Lastly, Tableau Prep Flow Authoring is about the creation and editing of data flow processes, which is distinct from retrieving and displaying metadata.
