In Azure AI Search, skillsets are AI tasks applied during indexing to enrich raw data (text, images, etc.) so it becomes more searchable and useful.
- 🔍 Built-in skills: AI features like OCR, language detection, key phrase extraction.
- ⚙️ Custom skills: Your own logic or API for custom data processing.
- 📄 Inputs/Outputs: Skillsets take in raw content and return enriched, structured data.
They help Azure AI Search understand and improve unstructured content.
