Hi,
I have a field and a wighted synonym map.
I have indexed the synonyms with the weight as payload.
my code snippet from my filter
*public Token next(final Token reusableToken) throws IOException *
* . *
* . *
* .*
* Payload boostPayload;*
*
*
* for (Synonym synonym : syns) {*
* *
* Token newTok = new Token(nToken.startOffset(),
nToken.endOffset(), "SYNONYM");*
* newTok.setTermBuffer(synonym.getToken().toCharArray(), 0,
synonym.getToken().length());*
* // set the position increment to zero*
* // this tells lucene the synonym is*
* // in the exact same location as the originating word*
* newTok.setPositionIncrement(0);*
* boostPayload = new
Payload(PayloadHelper.encodeFloat(synonym.getWieght()));*
* newTok.setPayload(boostPayload);*
*
*
I have put it in the index time analyzer : this is my field definition:
*
<fieldType name="PersonName" class="solr.TextField"
positionIncrementGap="100" >

<tokenizer class="solr.WhitespaceTokenizerFactory"/>

my similarity class is
public class BoostingSymilarity extends DefaultSimilarity {
public BoostingSymilarity(){
super();
}
@Override
public float scorePayload(String field, byte [] payload, int offset,
int length)
{
double weight = PayloadHelper.decodeFloat(payload, 0);
return (float)weight;
}
@Override public float coord(int overlap, int maxoverlap)
{
return 1.0f;
}
@Override public float idf(int docFreq, int numDocs)
{
return 1.0f;
}
@Override public float lengthNorm(String fieldName, int numTerms)
{
return 1.0f;
}
@Override public float tf(float freq)
{
return 1.0f;
}
}
My problem is that scorePayload method does not get called at search time
like the other methods in my similarity class.
I tested and verified it with break points.
What am I doing wrong?
I used solr 1.3 and thinking of the payload boos support in solr 1.4.
