Are you referring to the idf being local to the shard instead of global to the whole colleciton? Andrzej has a patch in the works, but it's not committed yet. > negative MTQ clauses may produce wrong results if the query rewriting is > done like in MultiSearcher (which is unsolveable broken and broken and > broken and again broken for some queries as Boolean clauses - see DeMorgan > laws). I don't think this is a problem for Solr. Queries are executed on each shard as normal (no difference from a non-distributed query). -Yonik http://www.lucidimagination.com --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
