Search default properties are ignored when at least one shard property exist
----------------------------------------------------------------------------

          Key: HSEARCH-239
          URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-239
        Project: Hibernate Search
      Issue Type: Bug
  Affects Versions: 3.0.0.GA
       Reporter: Rafal Glowacz


I'm trying to use shared strategy for search. So my basic setup was:

common.hibernate.search.default.indexBase = /lucene/index
common.hibernate.search.default.optimizer.operation_limit.max = 1000
common.hibernate.search.default.optimizer.transaction_limit.max = 1000
common.hibernate.search.default.directory_provider = org.hibernate.search.store.FSDirectoryProvider
common.hibernate.search.default.sharding_strategy = com.newbay.search.sharding.strategy.IdShardingStrategy

common.hibernate.search.blogentry.sharding_strategy.nbr_of_shards = 5

But this won't work for me because when sharding configuration properties exist then those default ones are completely ignored - I can't understand that. To change this I changed ".default." to ".blogentry." and then I found the bug that the number of properties decides how many shards I want for current index. (nbrOfShards = nbrOfShards >= indexSpecificDefaultProps.size() ?
                nbrOfShards :
                indexSpecificDefaultProps.size();)

So in this case I can't do anything. I'm looking for such config:

common.hibernate.search.default.indexBase = /lucene/index
common.hibernate.search.default.optimizer.operation_limit.max = 1000
common.hibernate.search.default.optimizer.transaction_limit.max = 1000
common.hibernate.search.default.directory_provider = org.hibernate.search.store.FSDirectoryProvider
common.hibernate.search.default.sharding_strategy = com.newbay.search.sharding.strategy.IdShardingStrategy

common.hibernate.search.website.sharding_strategy.nbr_of_shards = 2
common.hibernate.search.website.indexBase = /lucene/website
common.hibernate.search.blogentry.sharding_strategy.nbr_of_shards = 5
common.hibernate.search.blogentry.indexBase = /lucene/blogentry

But it doesn't work for now.

My solution for this is to build properties in order: default, indexProps, shardProps

//sharded
       nbrOfShards = nbrOfShards >= indexSpecificDefaultProps.size() ?
                nbrOfShards :
                indexSpecificDefaultProps.size();
       ensureListSize(indexSpecificProps, nbrOfShards);
for (int index = 0; index < nbrOfShards; index++) {
          Properties properties = new Properties();
          properties.putAll(defaultProperties);
          properties.putAll(indexSpecificDefaultProps);
          if (indexSpecificProps.get(index) != null) {
            properties.putAll(indexSpecificProps.get(index));
          }
          indexSpecificProps.set(index, properties);
       }
       return indexSpecificProps.toArray(new Properties[indexSpecificProps.size()]);
