Recoll / searching in multiple PDF files at once

#1 Post by debianix »

Hello!
I would like to perform a text-based search for keywords in multiple pdf files, because I think this is a very helpful feature.
Now I have discovered the package recoll and installed it directly via apt. I also added a few packages that should make it possible to search in Word documents, in case you ever come across something like this:

Code: Select all

sudo apt install recoll wv antiword
The package poppler-utils is apparently required for the PDF search and was already pre-installed.

I have now read here that it can also be integrated directly into KDE or Dolphin:
Unfortunately, I cannot find the "kio-recoll" package in the repos and am now wondering whether it is really not packaged under MX Linux or whether I have simply not looked hard enough?
If the package doesn't exist, is there any chance that it will come?

Code: Select all

+1 on pdfgrep .. I move so fast on files I just dont have time to sit and wait for recoll (or any app) to index them.

Also.. you do know that not all PDF's are searchable? They must have the text layer, which means some PDF's will need to be OCR'd to search.

Thanks for the tip, pdfgrep seems to me to be a tool that works well.
I have read the manpages and looked at some syntax examples. I installed and tested it, and it works so far, but I haven't figured out how to search ALL files ONLY within the current folder for a specific keyword / pattern / string .
Maybe someone can give me an example syntax for this? It should be a syntax in which the folder to be searched does not have to be specified, but which automatically refers to the folder in which you are currently located in the terminal.

Overall, I am very reluctant to work with terminal and file manager in combination, because I find it a bit cumbersome. There seems to be a GUI for pdfgrep, but I'm not quite sure how to assess this project in terms of security.

https://sourceforge.net/projects/pdfgrepgui/
I'm always used to such projects being on github etc. Sourceforge.net always reminds me more of windows .exe files ;)
What is your opinion?

The good news is that source code is there on sourceforge...

It will take a bit to walk through all the code, however, first glance it looks pretty good, and does compile and run under my Lazarus version as well. ( And it runs / looks very nice too! )

if you request this and link it in the requests area, one of the devs might be able to pick it up and verify all is good, and put it in the repos.

Your very welcome. And I agree with you on the GUI and pdfgrep.

The other search tool I use is fsearch.. and it is also amazing!
