Where it is: Knowledge → Add & Sources → Add Knowledge → WordPress content, with Products ticked. The WooCommerce sync switch is under Settings → Knowledge & Sync.
Run a content sync with Products ticked. Each product produces two things: searchable text, and a structured record with price, sale price, stock, rating, categories, attributes, variations and image.
Kept current automatically
Price changes, sale starts and stops, and stock movements from orders update the structured record immediately, without re-processing the text. So the bot never quotes yesterday’s price.
Product labels are indexed in your site language, so a Dutch shop is searched in Dutch. Non-English shops re-index their products once after upgrading to 1.54.
