--------------------------------
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.
Thanks,
DIGY
