Great post. Explains the concepts just enough that they click without going too deep, shows practical implementation examples, how it fits together. Simple, clear and ultimately useful. (to me at least)
We went with API embeddings for a similar use case. The cold-start latency of local models across multiple workers ate more money in compute than just paying per-token. Plus you avoid the operational overhead of model updates.
The hybrid approach in this article is smart. Fuzzy matching catches 80% of cases instantly, embeddings handle the rest. No need to run expensive vector search on every query.
FWIW, the performance considerations section is a little simplistic, and probably assumes that exact dataset/problem.
For GIN for example, perfomance depends a lot on the size of the search input (the fewer characters, the more rows to compare) as well as the number of rows/size of the index.
It also mentions GiST (another type of index which isn't mentioned anywhere else in the article)..
I was just starting to learn about embeddings for a very similar use on my project. Newbie question: what are pros/cons of using an API like gpt Ada to calculate the embeddings, compared to importing some model on Python and running it locally like in this article?
for 50,000 rows I'd much rather just use fzf/nucleo/tv against json files instead of dealing with database schemas.
When it comes to dealing with embedding vectors rather than plaintext then it gets slightly more annoying but still feels like such an pain in the ass to go full database when really it could still be a bunch of flat open files.

I found fuzzy search in Manticore to be straightforward and pretty good. Might be a decent alternative if one perceives the ceremony in TFA as a bit much.
