Hmm, so this was working with Gemini 1.0 until about a week ago when I had trouble and with Falco’s help I figured out that my project/key had an issue.
I created a new project and key using Gemini 1.5 pro (as best as I could figure out how to) and then I noticed this issue with the new key.
EDIT: Tried it again this morning, the xml tags have disappeared but the results are hard to use. It says here are 5 topics, but there are no links and under Search the only link presented is Found 5 results for ' order:latest'
