@kovid -- Just a suggestion to possibly increase compatibility with the new caliber search option


:
1. Although it's easy to redirect the search output (at least in DOS) to a temp file, maybe a --save <file> option to put the ID's into a file??
2. On some other calibredb options and maybe ebook-convert options add the ability to load the IDs from the above file??
Just a passing thought for your spare time
