Being able to query just a single shard or subset of shards would be awesome. I was thinking of a similar API: IndexShardingStrategy: public DirectoryProvider<?>[] getDirectoryProviderForShard(int shardNum); FullTextQuery: public void enableShardFilter(int shardNum); public void enableShardFilters(int[] shardNums); FullTextQuery.buildSearcher() would need to be modified to call getDirectoryProviderForShard() for each shardNum if shardNums are set, otherwise it should continue to use getDirectoryProvidersForAllShards(); Calling this API from a consumer's stand-point would look like: FullTextQuery fullTextQuery = fullTextSession.createFullTextQuery(luceneQuery, entityClass); fullTextQuery.enableShardFilter(5); fullTextQuery.list(); This could be changed to pass named shards easily. I could prototype this and submit a .patch if you are interested. -Chase -- This message was sent on behalf of chase.seibert+opensubscriber(a)gmail.com at openSubscriber.com http://www.opensubscriber.com/message/hibernate-dev@lists.jboss.org/98005...
