- We have on the order of a million lines of search code at this point and have a lot of talented people working them. That code does a myriad of things across many indexes.
- As an example, mobile searches are the largest category of searches, and local searches are the largest category of searches within mobile. We don't get any local search module content from Bing.
- Similarly, on desktop, knowledge graph / Wikipedia-type answers come up the most and we don't get any of that module content from Bing either.
- Bing is our largest source of traditional web links, which have become less and less relevant/engaged with over time as more and more modules are in search results and put on top of traditional links (and people interact with things on top of the search results page about two orders of magnitude vs. things on the bottom).
- When Bing has dropped things out of the traditional web index, we have put them back, and we've been working with them so this happens less and less. In fact, there hasn't been hardly any reports of this in the past month or so, which is why I've asked for other examples in the comments.
