Basically, the default operator "should" in boolean-clauses can be used exactly for that: do not force this query to be matched but raise boost if there's something that matches.
The translation of the user-query, itself, is marked as "must" (and inside this one is orred in all the various flavours, e.g. per language, phonetic...).

My initial description may have been a little abstract. Maybe I should explain exactly what I'm trying to do. My company has various revenue channels, one of which is per click. If a user does a search, we would like to show results with the greatest revenue, although we don't want people to be able to buy all the top results. Hence, we would like to have some way of mixing results. The mixing of results could be based of potential revenue, relevancy, which revenue stream the result is associated with, etc. The previously mentioned ideas are great btw. -MikeOn Sat, Oct 3, 2009 at 4:25 PM, Grant Ingersoll <gsing...@apache.org> wrote:I'm curious, can you elaborate more on the deeper use case for this?Perhaps just implementing faceting on doc type would be sufficient? That way users can drill in on doc type. Alternatively, I suppose you could implement a hit collector that accesses a field cache on the doc type field and promotes lesser seen doc types until they are evenly represented. Could also likely write a Function query that does a similar thing. I'd imagineyou need to be careful to control your memory. -Grant On Oct 1, 2009, at 12:56 PM, Michael Masters wrote:I was wondering if there is any way to control what kind of documentsare returned from a search. For example, lets say we have an index built from different types of documents (pdf, txt, html, etc.). Isthere a way to have the first x results have a specified distribution of document types? It would be nice to have an even number of resultsthat are from pdfs, txt files, and html files. Any help would greatly be appreciated. -Mike --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org-------------------------- Grant Ingersoll http://www.lucidimagination.com/Search the Lucene ecosystem (Lucene/Solr/Nutch/Mahout/Tika/Droids) usingSolr/Lucene: http://www.lucidimagination.com/search --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org--------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
