The first occurrence of your term does not have a payload, the second
one does. So getPayloadLength() correctly returns 0, because the
TermPositions is at the first occurrence. If you call nextPosition()
again and then dump the payload length it should be 1.

Hi
I don't know if it's supported or not, but I wrote the following
simple example code to describe what I want.
Directory dir = new RAMDirectory();
Analyzer a = new SimpleAnalyzer();
IndexWriter writer = new IndexWriter(dir, a,
MaxFieldLength.UNLIMITED);
Document doc = new Document();
doc.add(new Field("a", "abc", Store.NO, Index.NOT_ANALYZED));
final Term t = new Term("a", "abc");
doc.add(new Field(t.field(), new TokenStream() {
boolean done = false;
@Override
public Token next(Token reusableToken) throws IOException {
if (done) return null;
done = true;
reusableToken.setTermBuffer(t.text());
reusableToken.setPayload(new Payload(new byte[] { 1 }));
return reusableToken;
}
}));
writer.addDocument(doc);
writer.commit();
writer.close();
IndexReader reader = IndexReader.open(dir, true);
TermPositions tp = reader.termPositions(t);
tp.next();
tp.nextPosition();
System.out.println(tp.getPayloadLength());
reader.close();
Basically, I add the same Field twice (a:abc), the second time I just
set a Payload. The program prints 0 as the payload length (1 line
above the last). If I change either the field name or field text, it
prints 1.
Bug or works as designed?
