To enrich an index with language data of indexed documents, which Azure Cognitive Search object should be created?

To enhance an index with language data from the indexed documents, creating a Skillset is essential. A Skillset in Azure Cognitive Search acts as a collection of cognitive skills that enrich the content of documents in an index. These skills can involve natural language processing tasks such as language detection, key phrase extraction, or translation. When you apply a Skillset to documents during indexing, it processes the data and outputs enriched results that improve the quality and usability of the searchable content.

Skillsets are particularly important for scenarios where additional insights and understanding from the data are needed, which allows you to provide more relevant search experiences for users. By processing the text and language data using cognitive services, it enables the search capabilities to incorporate semantic understanding, making the search experience much more intuitive and effective.
