You can set up the search skill in Watson Assistant and create a collection from a data source. For instance, you can upload your HR information from your company's intranet, internal policy documents, FAQs, and other knowledge base repositories to help employees find answers to HR questions.

When users ask a question that the dialog skill is not designed to answer, Watson Assistant reviews the search skill for relevant information in the configured data sources. Watson Assistant extracts the information and return the information as a response.
