I've been able to create a very advanced search engine for my chat app that is more than enterprise ready. I've spent a decade thinking about search, but in a different language. Like you, I needed to explain what I knew about writing a search engine in Java for the LLM, to write it in JavaScript using libraries I did not know and it got me 95% of the way there.

It is also incredibly important to note that the 5% that I needed to figure out was the difference between throw away code and something useful. You absolutely need domain knowledge but LLMs are more than enterprise ready in my opinion.

Here is some documentation on how my search solution is used in my app to show that it is not a hobby feature.
