I put together an extensive guide to understanding embeddings and vector search last year: https://simonwillison.net/2023/Oct/23/embeddings/

Yes this is an excellent article, thank you.

Do embeddings work across languages? It must depend on the model, but are there models where similar concepts in different languages occupy the same location in vector space?

If yes it would allow to search a corpus in one language using another, without translating anything up front (neither the corpus nor the query).
