Re: [hibernate-dev] Hibernate search(lucene) update question & opinion.

Hi Emmanuel! First, I hadn't had the time till now to have a look at Hibernate Search, so sorry if this is some sort of "newbie question" .... Yes, I thought of a finer grained model, based on the content of the entity. Say you have a property named "type" in your entity, based on this type one might be able to create multiple smaller indexes. Very similar to what a database can do with partitioned tables. Now, to avoid any complex annotations we can hand the work to determine the partition to the DirectoryProvider (which I assume a user has to provide) Maybe by simply add the entity as argument to the directoryProvider.getDirectory() method so the provider could return a directory based on some sort of complex logic based on the entity. Then, we need an addition like directoryProvider.getDirectories() and create a MultiSearcher based on these directories. Now we can go even further (and I have done this in our Lucene Server). By caching the version of each of the directories, you are able to reopen only those indexes which have changed. So if the index changed, you do not have to open the whole index (which can be really large once you indexed plenty of text data - I've indexes with 1GB in size). I hope its clear what I wanted to say, else I can reword .... or even better ... can come up with a patch :-) Ciao, Mario
