Class HnswParameters

Contains the parameters specific to hnsw algorithm.

Inheritance

System.Object

HnswParameters

Namespace: System.Dynamic.ExpandoObject

Assembly: Azure.Search.Documents.dll

Syntax

public class HnswParameters

Constructors

HnswParameters()

Initializes a new instance of HnswParameters.

Declaration

public HnswParameters ();

Properties

EfConstruction

The size of the dynamic list containing the nearest neighbors, which is used during index time. Increasing this parameter may improve index quality, at the expense of increased indexing time. At a certain point, increasing this parameter leads to diminishing returns.

Declaration

public Nullable<int> EfConstruction { get; set; }

Property Value

System.Nullable<System.Int32>

EfSearch

The size of the dynamic list containing the nearest neighbors, which is used during search time. Increasing this parameter may improve search results, at the expense of slower search. Increasing this parameter leads to diminishing returns..

Declaration

public Nullable<int> EfSearch { get; set; }

Property Value

System.Nullable<System.Int32>

M

The number of bi-directional links created for every new element during construction. Increasing this parameter value may improve recall and reduce retrieval times for datasets with high intrinsic dimensionality at the expense of increased memory consumption and longer indexing time.

Declaration

public Nullable<int> M { get; set; }

Property Value

System.Nullable<System.Int32>

Metric

The similarity metric to use for vector comparisons.

Declaration

public Nullable<Azure.Search.Documents.Indexes.Models.VectorSearchAlgorithmMetric> Metric { get; set; }

Property Value

System.Nullable<VectorSearchAlgorithmMetric>
