@Deprecated
public class DirectUpdateHandler
extends UpdateHandler
```
DirectUpdateHandler implements an UpdateHandler where documents are added directly to the main lucene index as opposed to adding to a separate smaller index. For this reason, not all combinations to/from pending and committed are supported.

solr 0.9
