主题: Lucene in large database contexts

Hi There!

I've been working for a while on the implementation of a website
oriented to contents that would contain millions of entries, most of
them indexable (such as descriptions, texts, names, etc.).
The ideal solution to make them searchable would be to use Lucene as
index and search engine.

The reason I'm posting the mailing list is the following: since all
the entries will be stored in a database (most likely MySQL InnoDB or
Oracle), what's the best technique to implement a system that indexes
in "real time" (eg. when an entry is inserted into the databsse) the
content and make it searchable? Based on my understanding of Lucene,
such this thing is not possible, since the index must be re-created to
be able to search the indexed contents. Is this true?

Eventually, could anyone point me to a working example about how to
implement such a similar context?

Thank you for the support.
