Why does this ‘Overall Sentiment’ query gives empty results: [image]

I copied directly from Sara’s post and ran it and received results: [image] Can you confirm if you have data in your classification_results table?

[图片] Jordan Violet: I copied directly from Sara’s post and ran it I also just copied, pasted it as a ‘New Query’ and ran. No changes by me made at all. [图片] Jordan Violet: Can you confirm if you have data in your classification_results table? From where do I need to look for this? I’m…

[图片] Moin: That’s explained in the guide I quoted. Ok, I had missed, but now I’d surely study and solve the problem. Analysis was enabled in Feb or March, 2024, I don’t remember exact date. How many posts does it require (after its enabled, without running back-fill) to show something?
