Subject Re: Lucene index database

What Erick and Michael said are all correct, or the same. :)

What Lucene can do is search data that stored into Document objects.
Lucene is said to be able to search html, pdf, etc, but that's because
those formats are relatively fixed. You can easily tell title,
content, etc.

With database, which has more complicated and flexible structures. You
need to code to select data, retrieve content, save into Lucene index,
parse the queries, render the results, and also, keep the index in
sync with the database, etc.

You are welcome to try DBSight to save most of these repeated efforts.
