Hi,
I've been thinking for some time about integrating Cayenne ORM engine
with Lucene to provide database full text search capability that is
db-agnostic and works off of the Cayenne metadata. Now with the
Summer of Code approaching [1], this seems like a good idea of a
student project.
I have developed some simple programs in java form creating lucene indexes and
then using them to search. I now have an interest in using perl to use the
indexes for search purposes, but am having trouble doing even the simplest
thing using Plucene and Plucene::Simple. If anyone here can help,

Thanks, interesting... Certainly writing it from scratch doesn't look
trivial. Since Compass supports integration with many other ORMs, I
guess we may concentrate on writing a Compass Device for Cayenne then.

I don't understand what it means when this exception is thrown. I'm
quite certain that it is my skipTo(target)-code that causes it , but
I don't understand why. The FIXME and error message makes me think it
might be that I deliver the data ordered and it was not expected to be?

Karl,
If you get this one figured out, I'd be very happy. Unless I replace
the line reading
throw new RuntimeException(Unexpected: ordered);
with this one
return false;
I see plenty of these exceptions being thrown. I look forward to how
this plays out and if you are able to come
Hello
I am using span queries to get hits (Documents) and occurrences
(positions) of search terms within these documents.
For some reason, there is a disagreement between the order the

As marvin mentioned, there are some UTF-8 incompatabilities between java
lucene and Plucene.
Incidently: your best bet for getting assistence with Plucene is the
Plucene mailing lists, as identified at the bottom of perldoc Plucene ...

I have this general question about how to generate snippets (small piece of
information with search keywords in it) for any search results.
Is it something can be done by Lucene? Or does it require other
algorithms/packages?
Thanks,

Have a look at the Highlighter contrib library. It is used for the
search results here, for example:

Thanks a lot Hoss
The question is when I get Spans, I get start/end positions and a
Document order (starting from 0), not the Document object itself from
which I could get a filename. Since I believe there is no way to get a
Document object from Spans, and there is no such thing as Document

Are you sure about that? Spans.doc() should return you the internal
document Identifier which you can pass to indexReader.doc(int)
: which I could get a
The doc() number can be given to IndexReader.document() to get the
Document, I believe.

Of course. I'll pop it in the Jira as soon it passes all tests. If
someone wants to take a look right now, let me know.
Right now it's more of a branch than a couple of diffs. I might be
