So,for example, let’s say you search for something pretty niche like ‘how can I determine if my house windows are UV glass.’ This is a pretty tricky query, and we get lots of web pages that talk about UV glass and how you need a special film, but none of this really helps the layperson take action. Our new algorithm can zoom right into this one passage on a DIY forum that answers the question. Apparently, you can use the reflection of a flame to tell and ignores the rest of the posts on the page that aren’t quite as helpful.
