These are actually the same engine underneath, though, aren't they? Just with slightly different prompts? (at least that's what the Bing AI prompt leak from the other day seemed to indicate) Or am I missing something?
It seems to me like that would be covered under "query indices created by Bing's web crawling agents as they trawled live, reachable web pages around the Internet" because that's also what the regular Bing search engine does. I suppose one could argue that it's not really searching the web, but rather the Bing index which is then derived from the web. That really seems like a pointless distinction since you're just using the web index to leverage the preexisting engineering work to extract meaningful content.
