Digy commented on LUCENENET-415: -------------------------------- Hi Ben, About performance test: - One of the costly ops in this faceted-search is the creation of SimpleFacetedSearch. It creates the bit sets for all of the group members. Since it should be created only once when a new IndexReader is opened(if some documents are added or deleted), its creation time should be excluded from the test. - Another costly op is the fetching data from index. After each search, some data should be read and this duration should be included in the test. Eg. {code} TopDocs hits = sfs.Search(q, 100); for (int j = 0; j < hits.ScoreDocs.Length; j++) { Document doc = reader.Document(hits.ScoreDocs[j].doc); Fieldable f = doc.GetField("title"); } SimpleFacetedSearch.Hits hits = sfs.Search(q,maxDocPerGroup); foreach (var h in hits.HitsPerGroup) { foreach (Document doc in h.Documents) { Fieldable f = doc.GetField("title"); } } {code} - Hits is a deprecated class and it repeates the search every N (AFAIK 100) document access. It is not a "normal" search and should be excluded from the test.
