I feel like the answer is Yes, but I can't get it to work.
This is setup as an SP2016/O365 search hybrid with cloud ssa.
I have a result source like
and when searching for a phrase like
"red dog" it doesn't return anything. It does return if I search just
red dog, and I see the words red and dog next to each other in the hit highlights.
Using quotes against content stored in SharePoint Online sites works as expected, it's just the file shares crawled by Sp2016 which are acting up.
