Method Detail

searchModelByIndex

public com.hp.hpl.jena.rdf.model.NodeIterator searchModelByIndex(java.lang.String queryString)

Perform a free text Lucene search and return a NodeIterator.

Parameters:

queryString -

Returns:

NodeIterator

searchModelByIndex

public com.hp.hpl.jena.rdf.model.NodeIterator searchModelByIndex(com.hp.hpl.jena.rdf.model.Model model,
                                                                 java.lang.String queryString)

Perform a free text Lucene search and return a NodeIterator. The RDFNodes in the iterator are associated with the model supplied.

Parameters:

model -

queryString -

Returns:

NodeIterator

searchModelByIndex

public com.hp.hpl.jena.rdf.model.NodeIterator searchModelByIndex(com.hp.hpl.jena.rdf.model.Model model,
                                                                 java.lang.String queryString,

Perform a free text Lucene search and return a NodeIterator. The RDFNodes in the iterator are associated with the model supplied.

Parameters:

model -

queryString -

scoreLimit - Minimum Lucene score

Returns:

NodeIterator

hasMatch

public boolean hasMatch(java.lang.String queryString)

test whether the index matches for the given Lucene query string

search

public java.util.Iterator<HitLARQ> search(java.lang.String queryString)

Perform a free text Lucene search and returns an iterator of graph Nodes. Applications normally call searchModelByIndex.

Parameters:

queryString -

Returns:

Iterator of hits (Graph node and score)

contains

public HitLARQ contains(com.hp.hpl.jena.graph.Node node,
                        java.lang.String queryString)

Check whether an index recognizes a node.

Parameters:

node -

queryString -

Returns:

boolean

close

public void close()
