Does anyone know how to retrieve aggregated results from lucene? Is is possible to do something similar to this SQL statement below, which returns the numbers of books for each author for books published in 2007-2008?
select count(*), author_name from book where published_date >= '2007-01-01' and published_date <= '2008-12-31' group by author_name Note: I do NOT want to loop through every document to get these totals. Also note the "group by" and I am using two fields (author_name and published_date) so a simple TermEnum does not cut it. Thanks. -- View this message in context: http://www.nabble.com/aggregation-in-lucene-tp21041575p21041575.html Sent from the Lucene - General mailing list archive at Nabble.com.
