What type of skill enhances documents by combining various data sources into a single indexed document?

The Merge skill is designed to enhance documents by combining various data sources into a single indexed document. This skill is particularly useful in scenarios where information needs to be aggregated from multiple inputs to create a comprehensive output. For example, when multiple documents or datasets contain related information, the Merge skill allows you to consolidate those into one document, making it easier to index and search.

By consolidating various data sources, the Merge skill enhances the efficiency and utility of document processing in Azure AI solutions. It provides a streamlined way to manage data retrieval and ensure that users can access a complete set of information from a single indexed source, facilitating improved searchability and analysis.

Other skills, like Split or Filter, focus on other aspects of document processing but do not directly relate to combining or merging various data sources into one document. The Join skill, while it may imply a combination of inputs, typically applies more to relational data structures rather than directly enhancing documents in the context of indexing. Thus, the Merge skill is the most appropriate choice for the task described.
