Rather than loading all PDFs, create a generator pipeline:
def filter_keywords(stream: Iterator, keywords: set[str]) -> Iterator: for path, i, text in stream: if any(kw in text for kw in keywords): yield (path, i, text) Rather than loading all PDFs, create a generator
Modern Python strategy relies heavily on pytest . Rather than loading all PDFs
