Subject [Lucene.Net] [jira] [Updated] (LUCENENET-415) Contrib/Faceted Search
Date Mon, 23 May 2011 20:23:47 GMT

Ben West updated LUCENENET-415:
-------------------------------

    Attachment: facet performance.xls
                PerformanceTest.cs

I redid the tests, this time with no caching. The faceting is significantly (10x) slower in
big indexes. See "Round 2" in attached spreadsheet.

I tried your idea of doing it with boolean queries, and that seems to be much faster. If you
think that these stats are correct, we might want to consider doing facets in this style instead
of with the bitset. 

I tried to look at how Solr does it - I'm not familiar with their code, but it seems like
they do it with a DocSet.
