Search in RAMDirectory

Hi,

I want to switch from a FSDirectoryProvider to RamDirectoryProvider.
So in my hibernate.properties I have :

Code:

hibernate.search.default.directory_provider=org.hibernate.search.store.RAMDirectoryProvider

The indexation works well. But I do not manage to search in the index. I would like to get results of searchs in the RamDirectory as an Hits object using org.apache.lucene.search.Searcher.

Here is the code I wrote for FSDirectoryProvider :

Code:

Searcher idxSearcher = new IndexSearcher("myindex");          
Analyzer analyzer = new StandardAnalyzer();
QueryParser parser = new QueryParser("content",analyzer);           
String search = "name:" + searchString + " OR type:" + searchString + " OR subtype:" + searchString;
Query query = parser.parse(search);
Hits out = idxSearcher.search(query);

But this code is no longer working with the RamDirectoryProvider. I get an java.io.IOException when initializing the IndexSearcher.

What do I have to do to use a RamDirectoryProvider instead of the FSDirectoryProvider?

Thanks for you help!

In SVN Branch 3.2
Doing

Code:

Directory dir = ContextHelper.getSearchFactory(session).getDocumentBuilders().get(MyEntity.class).getDirectoryProvider().getDirectory();

IndexSeacher is = new IndexSearcher(dir);
...

If you use 3.2.1, the same info is available from the EventListener (it contains the list of document builders).

I know it's quite complex (probably need to improve that at some point through a helper method), but really the intend is to use FullTextSession and let Hibenate Search find the directory for you.

if FullTextSession does not solve your problem, let me know and I will enhance it.
