Hello Mike Thanks for the reply ,Now we are able to get TopGroups. but still we are not able to get score .how ever we got matched Parent and child through following code. We need score for showing in our application for ranking .
Document childDoc = indexsearcher.doc(group.scoreDocs[0].doc); Document parentDoc = indexsearcher.doc(group.groupValue); And Second Question is that, how does lucene score ? means we have used it before ,but the score is not between 0 to 1 example(16.0 or 1.4) so If i want to use it in percentage ..Then how it gonna work and the score is like this?
