Juraj Kucera created LUCENE-9017: ------------------------------------ Summary: GroupingSearch does not return all the groups when using SortedSetDocValuesField Key: LUCENE-9017 URL: https://issues.apache.org/jira/browse/LUCENE-9017 Project: Lucene - Core Issue Type: Bug Components: core/search Affects Versions: 8.2 Reporter: Juraj Kucera
I managed to retrieve the groups using the *SortedSetDocValuesField* in *GroupingSearch* by initializing the groupsearch with *SortedSetFieldSource* The problem is when a document has multiple values in the field "SortedSetDocValuesField" than not the grouping query does not return all the groups. Let me demonstrate it in my example // indexing, the first object has the category "one" and the second object has category "two" and "three" Document doc = new Document(); doc.add(new FacetField("Author", "Bob")); doc.add(new SortedSetDocValuesField("category", new BytesRef("one"))); indexWriter.addDocument(config.build(taxoWriter, doc)); doc = new Document(); doc.add(new FacetField("Author", "Lisa")); doc.add(new SortedSetDocValuesField("category", new BytesRef("two"))); doc.add(new SortedSetDocValuesField("category", new BytesRef("three"))); indexWriter.addDocument(config.build(taxoWriter, doc)); // initializing the grouping search ValueSource vs = new SortedSetFieldSource(groupField); groupingSearch = new GroupingSearch(vs, new HashMap<>()); // performing the group search TopGroups groups = groupingSearch.search(searcher, new MatchAllDocsQuery(), 0, 100); It returns 2 groups only and I would expect 3 groups ("one", "two" and "three") *Is it a bug or am I using the API in a wrong way?* -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
