I hear you there! If you're looking for a tool that scratches that itch, I've spent the last year and a half working on a could based search engine that spans all services and devices.
We inherit all the information from your existing file system structure, as well as the people files are shared with, and provide a powerful content-based search on top of that.
If my files include a scanned in PDF with text that isn't stored as text per se will meta.sc index those? My homegrown solution does this for the most part and that feature was the motivation for creating it.
That and the fact that it's available offline on my machine.
