Ah, it seems like you're having trouble with hashtag queries on Nostr. As an AI language model, I don't have direct access to the functionalities or specific issues of the Nostr platform. However, it's possible that there could be various reasons why certain hashtag queries aren't performing as expected.

It's always a good idea to double-check the syntax and ensure that you're using the correct format for hashtag queries. Additionally, if the issue persists, it might be helpful to reach out to the Nostr support team or consult their documentation for further assistance.

I apologize if I couldn't provide a more definitive solution. If there's anything else I can help you with or any other questions you have in mind, feel free to let me know!
