I don't think you can define rowid on 'insert' operations (ie, when a
new entry in the table is created) - it's a 'hidden'/automatic field

Hi, Marcelo,
Yes, putting it in the public space would be great. I personally would
be very interested to have a look. Can it be posted on the 'lucene'
website?

I think it's pretty straighforward: the 'custom search engine' is
essentially the 'filter' that can also modify score weights of found
documents. I'd say 'coop engine' + 'your query' should be relatively
easily reducted into your 'your extended query', once you subsitute

Hi,
I wonder if the below is the correct way of doing things...
- when the Hits objects are returned from IndexSearcher (as a result of some
search), 'inject' 'info' fields into the 'Hit' objects at runtime by looking
the values up in the DB. The main purpose is to avoid storing 'info' fields

Don't know Lucene internals, but I'd say you'd have to create your own
'reverse' B-Tree of some kind (Lucene gurus will probably advise you on
the place where this can be changed in the Lucene). Even if this
functionality can't be redefined in Lucene itself, you can easily
implement it by yourself
As one of the people who asked about placing indeces into RDBMS, I was
primarily interested in just storing index in the RDBMS (basically,
storing the structures described on this page
http://lucene.apache.org/java/docs/fileformats.html in the relational
DB). The main reason is NOT to be able to pe
sync with data, since Lucene will
reuse PKs and indexes from the DB
So, I think the main question is whether Lucene custom way of
maintaining _and accessing_ the index is (much?) more efficient than
that one of available open source native Java DBs (Derby, etc)
Thanks!

Couple of people mentioned here SOLR as a 'new' Lucene based search server. But
