I'm looking for a way to do a very specific task in Calibre but maybe it's not the right software.
I know there are plugins/functionality to automatically collect metadata for existing ebooks and to get information for fields such as Author, Title, Year of publication, Tags, all based on information taken from the file's name.
Is there a plugin/way for Calibre to scrape a bit of the book and try to match it's contents with some book through some search engine? Basically I want it to automatically scrape metadata without being constrained to the file name.
