Hi Andi,
Here is how you could retrieve positions from your document:
Terms termVector = indexReader.getTermVector(docId, fieldName);
TermsEnum reuse = null;
TermsEnum iterator = termVector.iterator(reuse);
BytesRef ref = null;
DocsAndPositionsEnum docsAndPositions = null;
while ((ref = iterator.next()) != null) {
docsAndPositions = iterator.docsAndPositions(null, docsAndPositions);
// beware that docsAndPositions will be null if you didn't
index positions
if (docsAndPositions.nextDoc() != 0) { // you need to call
nextDoc() to have the enum positioned
throw new AssertionError();
}
final int freq = docsAndPositions.freq(); // number of
occurrences of the term
for (int i = 0; i < freq; ++i) {
final int position = docsAndPositions.nextPosition();
// 'position' is the i-th position of the current term in the document
}
}
I hope this helps.
