Curious why specifically add multiple ranking steps to improve relevance? How would each ranking step differ ? Would you use different ranking models?

That's great feedback. The way it works right now is that I use Cloudflare AI Search to convert my image to text and embed the images. https://developers.cloudflare.com/ai-search/concepts/how-ai-...

Most of the descriptions generated for the images are likely generic and doesn't contain reference to the actual characters and names. I might explore incorporating some sort of more movie specific description in the metadata of the image to improve queries for specific characters.
