Something that is confusing to me is how to use embeddings outside of trivial use cases. Say you want to build something that takes a natural language query, then uses a heterogeneous data set with, say, three different types of data, such as text documents, database schema, and single phrase tags, and you want to create an embedding that maps that native language request to a particular table in a particular database. I have no idea where to begin.
