What a poorly written article that is contains a fair of amount of misinformation. I like you pretend to be a computer scientist on the internet.
If you weren't pretending you would know that basically every modern operating system does pre-indexed searching now out of the box. Even a low end computer with a modern operating system could search a 33 GB folder with in nearly real time for content not just filenames. So JSTOR service is very poor in comparison. But whatever, don't let facts get in the way of you pandering to JSTOR.
