Syntax

public abstract class Facets

Constructors

Facets()

Default constructor.

Declaration

protected Facets()

Methods

GetAllDims(Int32)

Returns topN labels for any dimension that had hits, sorted by the number of hits that dimension matched; this is used for "sparse" faceting, where many different dimensions were indexed, for example depending on the type of document.

Declaration

public abstract IList<FacetResult> GetAllDims(int topN)

Parameters

Type	Name	Description
System.Int32	topN

Returns

Type	Description
System.Collections.Generic.IList<FacetResult>

GetSpecificValue(String, String[])

Return the count or value for a specific path. Returns -1 if this path doesn't exist, else the count.

Declaration

public abstract float GetSpecificValue(string dim, params string[] path)

Parameters

Type	Name	Description
System.String	dim
System.String[]	path

Returns

Type	Description
System.Single

GetTopChildren(Int32, String, String[])

Returns the topN child labels under the specified path. Returns null if the specified path doesn't exist or if this dimension was never seen.

Declaration

public abstract FacetResult GetTopChildren(int topN, string dim, params string[] path)

Parameters

Type	Name	Description
System.Int32	topN
System.String	dim
System.String[]	path

Returns

Type	Description
FacetResult
