Same here. I was saving the article for when I have a few hours to really dive into it, build upon it, learn from seeing and doing. Imagine my disappointment when I had the evening cleared, started reading, and discover all they're showing is how to concatenate a string, download someone else's black box model which outputs the similarity between the user's query and the concatenated info about each object, and then write queries on the output

It's good to know you can do this performantly on your own system, but if the article had started out with "look, this model can output similarity between two texts and we can make a search engine with that", that'd be much more up front about what to expect to learn from it

Edit: another comment mentioned you can't even run it yourself, you need to ask ClosedAI for every search query a user does on your website. WTF is this article, at that point you might as well pipe the query into general-purpose chatgpt which everyone already knows and let that sort it out
