Web Search - Anyone figured it out yet?

[Rebekka Heilmann _viadee_]

The web search button has been available to us for a while now, but I still can't figure out if/how it works.

Does is actually search the web? Does it only search connected websites (through Rovo connectors)?

Tried different prompts but not got a good answer nor a Web page as source once. Also, couldn't find any info on it in official documentation. Maybe I am missing something here...
