TermFreqVector

I need to use getTermFreqVector on a subset of docs that
belong to the hits for a query. I understand I need to pass
the docNumber as an argument in this case. How do I access
that.

For ex .

doc = hits.doc(0);
TermFreqVector vector = reader.getTermFreqVector(docId,
"field");


How do I get docId?

If you use Hits, it is hits.doc()

hits.id() should work.

ml#id(int)

public final int id(int n)
             throws IOException

    Returns the id for the nth document in this set. Note
that ids may
change when the index changes, so you cannot rely on the id
to be
stable.
