I'm trying to find some text within PDF files, but the results are not accurate! For exemple I have 2 PDF files which have the word domiciiado. When I run a search for this word (domiciliado), docfetcher shows only ONE PDF file with this word. My question is why docfetcher doesn't show the other PDF file with this word? Is there a difference between PDF files? In one PDF I have only text and the other PDFs are texts and images and this is from a scanned page. What is the catch?
Listing 1 shows how to unpack the ZIP archive downloaded from the project page into the /usr/local/bin/ directory. In Listing 2, you will find the content for /usr/share/applications/docfetcher.desktop to help you create a matching entry in the Start menu of the desktop environment.
Adjust the version number in the commands if necessary. If you prefer a location other than /usr/local/bin/docfetcher/, remember to change the paths appropriately. If you are still using a system without GTK3 libraries, you also need to swap DocFetcher-GTK3.sh for DocFetcher-GTK2.sh in the Exec line.
Thinking about it, maybe someone could produce a plugin that called docfetcher (or another program/libraries) and allowed the text to be searched and used in Obsidian. That would be a plugin rather than a feature though.
