Semantic search
Semantic search retrieves information based on relationships of meaning, as well as literal word matches
What it means, how it is used and where it comes up, with its related concepts.
What it is and how it works
It can use vector representations and other methods. It helps find content expressed in different ways. It should be evaluated with real queries, since interpreting an approximate relationship can introduce irrelevant results or miss important details of the question.
