@Charles Azure Cognitive Search provides two ways to ingest documents: using the upload wizard or using Azure AI Document Intelligence.
The upload wizard is a simple and straightforward way to upload documents to your search index. You can upload documents individually or in batches, and you can map fields in your documents to fields in your search index. This method is suitable for small to medium-sized document collections and for users who want to have full control over the ingestion process.
On the other hand, Azure AI Document Intelligence is a more advanced and automated way to ingest documents. It uses machine learning models to extract information from your documents and enriches them with metadata. This method is suitable for large document collections and for users who want to automate the ingestion process and extract valuable insights from their documents.
To elaborate Azure AI Document Intelligence is a cloud-based Azure AI service that enables you to build intelligent document processing solutions. Massive amounts of data, spanning a wide variety of data types, are stored in forms and documents. Document Intelligence enables you to effectively manage the velocity at which data is collected and processed and is key to improved operations, informed data-driven decisions, and enlightened innovation.
Hope this helps.
