Yes that is true. However this shortcut did help me looking into the notebooks. A custom iFilter should make things better. Going through the extension and their filters it seems only the standard txt filter is used. No idea if Wolfram research is designing a custom filter.
Thank you, I'll try this. However, I expect it to be a little less efficient, as it'll search the entire notebook contents, which include images, compressed data, etc. I'd think an iFilter designed for notebooks would skip over such content.
Can someone tell me how can I just use Plain Text IFilter with nb format? Since I am also getting Registered IFilter is not found. I am fine with just using a plain text filter but don't know how to associate the plain text filter with nb format.
Spelunking on StackExchange suggests WDS capability was lost back around v10.2. It is a painful loss.
