Hello, I'd like to know which field got hit in each doc in the hit results. To implement it, I thought I could use Scorer.freq() which was introduced 3.1/4.0:
https://issues.apache.org/jira/browse/LUCENE-2590 But I didn't become successful so far. What I did is: - in each visit methods in MockScorerVisitor (borrowed TestSubScorerFreqs), if child query is TermQuery (for simple PoC), add the pair of child query and scorer in a collection: if (collect.contains(Occur.MUST_NOT) && child instanceof TermQuery) tqsSet.add( new TermQueryScorer( (TermQuery)child, scorer ) ); where tqsSet is: Set<TermQueryScorer> tqsSet = new HashSet<TermQueryScorer>(); and TermQueryScorer is: private static class TermQueryScorer { private TermQuery query; private Scorer scorer; public TermQueryScorer( TermQuery query, Scorer scorer ){ this.query = query; this.scorer = scorer; } } - in collector.collect() method: public void collect(int doc) throws IOException { int freq = 0; for( TermQueryScorer tqs : tqsSet ){ Scorer scorer = tqs.scorer; int matchId = scorer.docID(); if( matchId == doc ){ freq += scorer.freq(); } } docCounts.put(doc + docBase, freq); collector.collect(doc); } But freq was always zero. In collect() method of TestSubScorerFreqs, scorer is BooleanScorer2, then the matchId == doc condition is true. But in my case, matchId which is got from TermScorer never equal to doc. Can I use the feature of LUCENE-2590 to know not only freq but also which field got hit?
