Marcel Reutegger updated JCR-1747:
----------------------------------

    Attachment: JCR-1747.patch

The attached patch introduces a DirectoryManager interface. There are two implementations currently:

- FSDirectoryManager, this is the default, which matches the current behaviour
- RAMDirectoryManager, this one allows you to have an index that is completely held in memory

> If I'm not wrong, there is actually no way to configure SearchIndex in order to use a memory only lucene index.
> Since you can configure a repository using a org.apache.jackrabbit.core.state.mem.InMemPersistenceManager, it makes sense that also search index offers a similar configuration.
> MultiIndex and PersistentIndex now always use a org.apache.lucene.store.FSDirectory, they should be refactored in order to allow a switching to a org.apache.lucene.store.RAMDirectory for this.
