Analyze multiple documents all at once, either by passing a list of Document IDs or by passing a dataset name. If both are pased, we will use the intersection of the two. Analysis works by passing a list of questions in natural language. If a schemaId is passed, the AI will first use the standardizations of those documents under the provided schema to narrow down which documents are relevant. Only then, it will analyze the documents and provide answers to the questions, along with confidence scores and citations. If a schemaId is not passed, the AI will manually examine all documents, with a limit of 50. When schemaId is passed, the AI can optionally also perform database queries for statistical calculations and answer the questions based on those results.
