Design AI-Powered Document Search
Design AI-Powered Document Search
Design a system that allows users to upload documents (PDFs and common office formats) and later search them using a combination of structured fields and free-text keywords. The system must leverage a multi-step AI pipeline to extract metadata, document fields (e.g., type, vendor, date), and relevant search keywords from the uploaded documents. The system should support fielded queries like vendor = Acme AND keyword = renewal, return low-latency search results, and highlight matching terms. Crucially, the system needs to handle intermittent failures in OCR or AI services gracefully through reliable asynchronous processing. Discuss data storage, indexing strategies, orchestration, retry mechanisms, reprocessing of documents, and monitoring.
