Method Detail

newDocumentRepresentingProperty

public org.apache.lucene.document.Document newDocumentRepresentingProperty(long nodeId,
                                                                  org.apache.lucene.document.Fieldable encodedValue)

encodeAsFieldable

public org.apache.lucene.document.Fieldable encodeAsFieldable(Object value)

newScanQuery

public org.apache.lucene.search.MatchAllDocsQuery newScanQuery()

newSeekQuery

public org.apache.lucene.search.TermQuery newSeekQuery(Object value)

newInclusiveNumericRangeSeekQuery

public org.apache.lucene.search.TermRangeQuery newInclusiveNumericRangeSeekQuery(Number lower,
                                                                        Number upper)

Range queries are always inclusive, in order to do exclusive range queries the result must be filtered after the fact. The reason we can't do inclusive range queries is that longs are coerced to doubles in the index.

newRangeSeekByStringQuery

public org.apache.lucene.search.TermRangeQuery newRangeSeekByStringQuery(String lower,
                                                                boolean includeLower,
                                                                String upper,
                                                                boolean upperInclusive)

newRangeSeekByPrefixQuery

public org.apache.lucene.search.PrefixQuery newRangeSeekByPrefixQuery(String prefix)

newTermForChangeOrRemove

public org.apache.lucene.index.Term newTermForChangeOrRemove(long nodeId)

getNodeId

public long getNodeId(org.apache.lucene.document.Document from)
