Given:
- A directory with 1..n ZIP files of random names (all ending with .zip)
- Each zip file contains 1..n PDF files of random names (all ending with .pdf)
- All PDFs are from the same source and are to some extend comparable formatted.
- The PDFs are no prosa text but rather invoices, inventory lists etc. (aka forms and tables; The PDFs are searchable when I open them in an PDF viewer.)
- A search term i.e. a stock item number or a invoice number
Wanted:
- A way to find/list all the PDFs that contain the given search term.
- preferably with existing linux tools.

You can convert the PDF to text and then apply grep on that text:
#!/bin/bash
for z in *.zip
do zipinfo -1 "$z" | # Get the list of filenames in the zip file while IFS= read -r f do unzip -p "$z" "$f" | # Extract each PDF to standard output instead of a file pdftotext - - | # Then convert it to text, reading from stdin, writing to stdout grep -q 1234 && echo "$z -> $f" # And finally grep the text done
done
