df (DuplicateFilter) is the second parameter in the searcher.search metod.
>> ScoreDoc[] hits = searcher.search(q, df, 1000).scoreDocs;
This varians doesn't hit too:
ScoreDoc[] hits = searcher.search(new FilteredQuery(tq, df), new
QueryWrapperFilter(new TermQuery(new Term("text", "now"))),
1000).scoreDocs;
Or:
ScoreDoc[] hits = searcher.search(new FilteredQuery(tq, new
QueryWrapperFilter(new TermQuery(new Term("text", "now")))), df,
1000).scoreDocs;
