score property
Score is the cosine similarity between the query's embedding and the document's, from -1 to 1, higher being closer — the collection is created with Cosine distance. Hits arrive ordered by it, descending. There is no absolute cutoff: what counts as a good score moves with the query and the embedding model, so compare scores within one response and not across queries.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
num? score;
