Yep! In the search field above the library window, press the "FT" button on the very left. You have to create the index the first time you use the feature. It takes a while and from there on new books are indexed automatically.
FT search has word and phrase search, boolean operators and NEAR search abilities. And there is a really cool match list, giving some context of the match before you actually go to it in the PDF file.
You cannot search across libraries, though.

- ggpsv 3y agoI've had good luck using Tesseract [0] for scanned PDFs. If you're not CLI-inclined, there are several GUIs for it available [1]. I have had good luck downloading scanned PDFs from archive.org and running them through Tesseract. Did not know about Calibre for this - I was relying on opening each search and searching it individually.

- kristofferR 3y agoOCRmyPDF is a tool using Tesseract, specifically designed for PDFs. I would recommend that over pure Tesseract. https://github.com/ocrmypdf/OCRmyPDF https://github.com/ocrmypdf/OCRmyPDF
- kristofferR 3y agoI recommend running any such PDFs through OCRmyPDF. https://github.com/ocrmypdf/OCRmyPDF https://github.com/ocrmypdf/OCRmyPDF
- Fluorescence 3y agoOh, lol, I never knew that. I created a script that dumped my library of 1000s of books to .txt and then grepped them.
