An overview of the Calibre search syntax is available here. Search supports basic searches, e.g., for single words and phrases, but also Boolean searches and phrases near others. Once books are indexed, Calibre will run full text searches across the entire library whenever the search function is used. The fast indexing speed option requires more resources, but it finishes indexing operations faster. If you use calibre to manage your ebook library and are fond of its ebook reading function, you might want to hold off on the latest update. The default indexing speed is set to slow, which is done to limit the impact on the computer when the indexer runs. Select the FT icon next to the search field in Calibre's interface and check the 'index books in this library to allow searching their full text' option when the configuration window opens. Calibre can be configured to index the text of all books in the library to make it searchable. IIRC there was no way to provide such a plugin and tell Calibre it should only be used for conversion. It could be that the ebook-viewer just picked up the DjVu plugin by using the same interface as the convertor, that would make sense, but in the case of DjVu files that is not the right approach. It goes to the Kindle fine over email but no cover. It shows nothing, which confirms my expectation. What I am having trouble with is having no book cover when I go through the above steps. I usually have an ebook in epub format and convert to mobi and then back to epub. Calibre 6.0 supports Apple Silicon CPUs on Mac OS devices and ARM CPUs on Linux.Īnother main improvement is the ability to run full text searches using Calibre's indexing functionality. I have a Kindle Paperwhite and use Calibre with the add on DeDrm Tool.

The new version of the ebook software supports new CPU architectures.
