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

override this.GetNearestMatchAsync : string * ReadOnlyMemory<single> * double * bool * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Nullable<ValueTuple<Microsoft.SemanticKernel.Memory.MemoryRecord, double>>>Public Function GetNearestMatchAsync (collectionName As String, embedding As ReadOnlyMemory(Of Single), Optional minRelevanceScore As Double = 0, Optional withEmbedding As Boolean = false, Optional cancellationToken As CancellationToken = Nothing) As Task(Of Nullable(Of ValueTuple(Of MemoryRecord, Double)))Parameters
- collectionName
- String
in the case of Pinecone, collectionName is synonymous with indexName
- embedding
- ReadOnlyMemory<Single>
The embedding to search for
- minRelevanceScore
- Double
The minimum relevance score to return
- withEmbedding
- Boolean
Whether to return the embeddings with the results
- 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.
