Gets the nearest match to an embedding of type Single. Does not guarantee that the collection exists.

- collectionName
- String
The name associated with a collection of embeddings.
- embedding
- ReadOnlyMemory<Single>
The embedding to compare the collection's embeddings with.
- minRelevanceScore
- Double
The minimum relevance threshold for returned results.
- withEmbedding
- Boolean
If true, the embedding will be returned in the memory record.
- cancellationToken
- CancellationToken
The CancellationToken to monitor for cancellation requests. The default is None.
Returns
A tuple consisting of the MemoryRecord and the similarity score as a Double. Null if no nearest match found.
