Hello, Greg,

Indeed, there is an issue with searching in this large data scenario. The reason is that once the search tool is opened, the PDF Viewer renders the entire content (initially the component only renders a small subset of hte pages). Then, the search itself works with regex, which would be inevitably slow operation in a large document. 

I'm converting this thread to a Feature Request, in order to investigate an alternative of the searching functionality and enhance it.

Regards,
Nencho
