Search for keyword in files in Apache directory listing?

[CP30126]

Hello. This webpage\directory ( http://collections.banq.qc.ca:8008/lapresse/ ) contains a lot of old newspapers in the form of PDF and TXT files. I'd like to find every newspapers that contains the word "olivetti" in them. So, are there any programs that could search every TXT or PDF files in the entire directory for the word "olivetti" and then tell me where they are?

I really hope such programs exist....
