I need a Linux GUI application in which I can search my home folder for all of documents that contain a particular word/sentence.
- Obviously, it must work with text files.
- It must also work with MS Office and OpenDocument files.
- Moreover, it must work with PDF/TIFF/JPG/DjVu files, even those that are pure images, that means that the indexer must perform OCR recognition on the content of these files.
Ideally open source, but up to 50 USD per year per user is also OK.
