Thanks @yaoqih!

I also noticed this one, but I can't see the problem in the markdown:

Wow, you are really attentive. I carefully compared the English and Chinese versions, and the formulas are exactly the same. However, the Chinese version is missing a space before the formula. I'm not familiar with the embedding rules for follow and markdown formulas; do I need to add a space before the formula?"

Strange, I see the space in the Chinese version as well \\( N \\) 是查询的数量，\\( d_{\text {key }} \\) 是每个查询的维度。. Not sure what's going on, but feel free to add it and see if it solves it!

I guess I need to add spaces before the formula so that the formula can be separated and recognized correctly. I have added spaces. Please try again.

It worked :) Thanks @yaoqih 🙌
