Thank you, Mike. Are you sure the 'Solr' has implemented 'Join' function. I just skims through some tour guids about Solr, and not sure about that. Appreciate you very much.
I figure out another way to handler this problem. Our system also has duplication of these articles and the records(about who and when edit this article) in the database, so, I shall search the data with 'time range' condtion in the database first, then, use a Lucene Filter to get right results. SELECT DISTINCT article_ids FROM records r WHERE r.edit_date > '2011-09-23' and r.edit_date < '2011-10-19' and r.user_id='000000_editor_id' and, the article_ids will pass into Lucene to filter the search results. Althought it's a little clumsy and stupid, it can work for this case.
