How are you guys getting a web search from the zorin start menu or the zorin overview screen? Are you just using Google Search Provider? It looks like it's busted?
Similar to the 2015 Windows 10 release, web search capabilities in the Zorin Search input field... either from taskbar "left menu" (zorin logo) or the "Activities Overview" search input field.
I had to run a command to enable the Gnome Extensions and do a system restart. After I did that, I could install the gnome search and the search inside gnome shell works.
