Hey Everyone,

I was having a look through data.gov.au and I found the basic search results to be pretty unusable.
Would it be a bad idea to explore using document embeddings + vector similarity in elastic in order to surface even more relevant results?
See elastic article on it here: Text Embeddings and Vector Search with elastic
