Cross-Document Search for Mobile Devices

On mobile devices like the iPhone, searching for specific words or phrases across multiple document types (PDFs, Word files, text files, scanned images via OCR) stored locally or in various cloud services is a significant pain point. A SaaS could offer a universal mobile document search and indexing app. It would integrate with common cloud storage solutions and local files, automatically index the content of various document formats, and provide a single, powerful search interface to quickly locate information regardless of its original file type.
