I'm guessing it's broken because Bing updated their interface, related to all this ChatGPT stuff that's coming soon. Anyway, it does not seem to work for me as of yesterday. I am able to use Bing from a browser so I'm not being blocked or anything like that. Also tried the YahooSearch version, with its additional "all' parameter - same thing, empty results only.
Hmm....seems to work. Maybe was temporary issue sorry. Can you just delete my post above thx - Ted
I had the same experience when trying to fix it - first broken, then worked. I couldn't fix the "Related searches" view however, so this has been removed in newest version of the connector.
