Simple script to search for a collection of key-terms and abbreviations across a bundle of PDFs.
Create the project environment via conda + env_pdf_kt.yaml,
or adapt the YAML contents to a requirements.txt and use venv, poetry, etc.
Drop one or more PDF files and/or folders thereof into the docs directory, then run the script.
Returns a CSV with file name, key_term, page_num, and frequency values,
where freq quantifies the number of key_term matches on a given file's page_num.
