Paul Elschot commented on LUCENE-2454:
--------------------------------------
With these rewrite and createWeight methods TestNestedDocumentQuery passes:
{code}
+ @Override
+ public Query rewrite(IndexReader reader) throws IOException {
+ Query rewrittenChildQuery = childQuery.rewrite(reader);
+ return (rewrittenChildQuery == childQuery) ? this
+ : new NestedDocumentQuery(rewrittenChildQuery, parentsFilter, scoreMode);
+ }
+
+ @Override
+ public Weight createWeight(IndexSearcher searcher) throws IOException {
+ return new NestedDocumentQueryWeight(childQuery.createWeight(searcher));
+ }
+
{code}
I'll continue adding the use of prevSetBit.
Would modules/grouping meanwhile be a better place for this than
lucene/contrib/queries?
