| <div class="markdown level0 summary"><p>BlockGroupingCollector performs grouping with a |
| single pass collector, as long as you are grouping by a |
| doc block field, ie all documents sharing a given group |
| value were indexed as a doc block using the atomic |
| <a class="xref" href="http://localhost:8080/api/core/Lucene.Net.Index.IndexWriter.html#Lucene_Net_Index_IndexWriter_AddDocuments_System_Collections_Generic_IEnumerable_System_Collections_Generic_IEnumerable_Lucene_Net_Index_IIndexableField___Lucene_Net_Analysis_Analyzer_">AddDocuments(IEnumerable<IEnumerable<IIndexableField>>, Analyzer)</a> or |
| <a class="xref" href="http://localhost:8080/api/core/Lucene.Net.Index.IndexWriter.html#Lucene_Net_Index_IndexWriter_UpdateDocuments_Lucene_Net_Index_Term_System_Collections_Generic_IEnumerable_System_Collections_Generic_IEnumerable_Lucene_Net_Index_IIndexableField___Lucene_Net_Analysis_Analyzer_">UpdateDocuments(Term, IEnumerable<IEnumerable<IIndexableField>>, Analyzer)</a> |
| API.</p> |
| <p><p> |
| This results in faster performance (~25% faster QPS) |
| than the two-pass grouping collectors, with the tradeoff |
| being that the documents in each group must always be |
| indexed as a block. This collector also fills in |
| TopGroups.totalGroupCount without requiring the separate |
| <a class="xref" href="Lucene.Net.Search.Grouping.Terms.TermAllGroupsCollector.html">TermAllGroupsCollector</a>. However, this collector does |
| not fill in the groupValue of each group; this field |
| will always be null. |
| </p> |
| <p> |
| <code>NOTE</code>: this collector makes no effort to verify |
| the docs were in fact indexed as a block, so it's up to |
| you to ensure this was the case. |
