How bad the search features in outlook and teams are, is part of the reason I don't bother trying Bing. If you can't get local search right, global search is going to suck too.
Aye, I was being at least a little facetious. The team of indexing global content is quite different to that of searching my local mail and chat logs. The various "English language search" features attempted for SQL Server are different again.
But they are still all search functions, and the Outlook & Teams search functions seem so terrible that you'd think they'd try do something about it to support the pubic view of their other search related efforts.
