> Because IdHashShardingStrategy fails after 1.7m ID is reached I decided to use my own version of strategy. I set up property common.hibernate.search.blogentry.sharding_strategy = com. ... .IdShardingStrategy and didn't work for me. As I checked problem exist in DirectoryProviderFactory and the way how properties are created ( new Properties( defaultProperties ) ). This constructor and the way how default properties are stored in this Object this both together doesn't work well. Problem exist:
> //define sharding strategy
> IndexShardingStrategy shardingStrategy;
> Properties shardingProperties = new Properties();
> for (Map.Entry entry : indexProps[0].entrySet()) {
> if ( ( (String) entry.getKey() ).startsWith( SHARDING_STRATEGY ) ) {
> shardingProperties.put( entry.getKey(), entry.getValue() );
> }
> }
> String shardingStrategyName = shardingProperties.getProperty( SHARDING_STRATEGY );
> if ( shardingStrategyName == null) {
> if ( indexProps.length == 1 ) {
> shardingStrategy = new NotShardedStrategy();
> }
> else {
> shardingStrategy = new IdHashShardingStrategy();
> }
> }
> else {
> in this loop "for (Map.Entry entry : indexProps[0].entrySet()) {" this set is just empty so custom properties for sharding have been ignored. 
> Workaround:
> Instead using new Properties(defaultProps) I'm using method:
>     private static Properties createProperties(Properties indexSpecificDefaultProps) {
>         Properties properties = new Properties();
>         properties.putAll(indexSpecificDefaultProps);
>         return properties;
>     }
