Which entity is set up to use the knowledge search functionality by default?

The entity that is set up to use the knowledge search functionality by default is the Case entity. This is primarily because cases represent issues or inquiries raised by customers, and organizations often rely on knowledge base articles to quickly provide solutions to these issues. The knowledge search functionality is a crucial tool in the customer service framework, enabling agents to find relevant articles that can help resolve cases efficiently.

By utilizing the knowledge base, customer service representatives can enhance their productivity, reduce resolution times, and increase customer satisfaction by providing accurate information quickly. While other entities like Lead, Account, and Contact are important in the overall customer relationship management process, they are not typically associated with the immediate need for knowledge search functionalities in the same way that cases are.
