Method Details

score

public float score(int node)
            throws IOException

Description copied from interface: RandomVectorScorer

Returns the score between the query and the provided node.

Specified by:

score in interface RandomVectorScorer

Parameters:

node - a random node in the graph

Returns:

the computed score

Throws:

IOException

maxOrd

public int maxOrd()

Specified by:

maxOrd in interface RandomVectorScorer

Returns:

the maximum possible ordinal for this scorer

ordToDoc

public int ordToDoc(int ord)

Description copied from interface: RandomVectorScorer

Translates vector ordinal to the correct document ID. By default, this is an identity function.

Specified by:

getAcceptOrds in interface RandomVectorScorer

Parameters:

acceptDocs - the accept docs

Returns:

the accept docs
