Lesson 2: Reading PDFs, office files and email without losing answers

Module 2 · Lesson 2 · About 45 minutes · Needs: Lesson 1 of this module (raw files and loaders)

The situation

Kwame has a confession. In the prototype, the P9 quick-start page was typed in by hand from the PDF, which is why "how loud is the P9 on the night setting" (question q24) worked. The real manuals folder holds PDFs, some of them scans of old printed guides, Word drafts, a training deck, the parts list as CSV and spreadsheet, and partner email. Nobody will type those in.

Your job: load every format so that the answer to q24, the table row "Night, 60 m3/h, 24 dB", reaches the index intact, and so that a file you cannot read is refused with a reason, not indexed as nonsense.
