1) I don't understand why the index would get corrupted. We store
huge data
and meta-data using Lucene.
I got that information when lucene 1.4 was the lastest version, may
have changed. I'll trust you.
2) For this, I synced Lucene with the DB operations. If you use
Hibernate,
theres an API for that. Or, you could just write your own factory
methods to
add/delete/edit index documents when a DB operation takes place
(e.g edit).
You mean every time you update the db, you update the index also ?
I'm actually planning not to use any external entity, and rely
everything on Lucene. Wondered if some simple query (get the lastest
document for example) would solve the versioning issue
Thanks a lot

Hello,
We're starting a new project, which basically catalogs
everything
we
have in the department (different objects with different metadata),
and as I used Lucene before, I'm preparing a presentation to the
team, as I think it would really simplify the storage of metadata and
documents.
The system will be pretty straightforward, all items will be
cataloged, and most of them won't be changed too much ( I'll raise
this question later ).
So, here are my main concerns, hope you can help
1) Storing all data (index and content) wasn't recommended in the
past, as the index could become corrupted. Do I have this problem if
I use a JdbcDirectory (PostgreSQL backend) ? I already read about the
performance degradation when using a database as main storage, but
this won't be a problem.
2) Lucene doesn't support incremental editing (a new Document will be
created when someone edits an item), so is it possible to manage some
kind of versioning ? Anyone ever implemented something this way ?
Thanks a lot for the attention
