How it works
"How do I fix a leaking faucet?" works. So do misspellings like "refridgerant". The search knows the manuals call a toilet a water closet.
Answers come only from the manuals. Each step links to its page, and the page opens with your words highlighted.
Schools and training programs can get seats for a whole class with one access code.
