Method Summary

Modifier and Type	Method	Description
default Bits	getAcceptOrds(Bits acceptDocs)	Returns the Bits representing live documents.
int	maxOrd()
default int	ordToDoc(int ord)	Translates vector ordinal to the correct document ID.
float	score(int node)	Returns the score between the query and the provided node.

Method Details

score

float score(int node)
     throws IOException

Returns the score between the query and the provided node.

Parameters:

node - a random node in the graph

Returns:

the computed score

Throws:

IOException

maxOrd

int maxOrd()

Returns:

the maximum possible ordinal for this scorer

ordToDoc

default int ordToDoc(int ord)

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

Parameters:

ord - the vector ordinal

Returns:

the document Id for that vector ordinal

getAcceptOrds

default Bits getAcceptOrds(Bits acceptDocs)

Returns the Bits representing live documents. By default, this is an identity function.

Parameters:

acceptDocs - the accept docs

Returns:

the accept docs
