Thanks Erik. I am continuing to experiment and making good progress. I
have got my basic functionality established and am now looking at
sorting and ranking. I guess the good thing is I can adjust and modify
things as I learn more. I am reading some archived material from the
list as well to get a general sense of issues that have come forward. I
managed to get a powerpoint from apachecon on advanced techniques. This
kind of materialhelps to understand what is possible and to discover
how dynamic Lucene really is.
Regards,
David

Hi Erik. Many thanks for your reply. I'll likely see if I can find a
list to pose a couple of questions there way. I am having fun with
Lucene since it is new to me and I am impressed with the speed I am
getting. I am reading anything I can get hold of and trying different
code experiments. So far, the code is fairly straight forward so not
so concerned about this at the moment.
I am really hoping to hear from experienced people like yourself more
on strategically what to index, what sort of things it would be a
good idea to store and what to do about a fairly large schema that
has much metadata to offer. Also perhaps when sorting and filtering
gets too expensive. I realize that just because the metadata is
available doesn't necessarily mean you want to even put it all in an
index. I think these issues are pretty general, however I know there
are folks on this that would likely advise some particular path or
direction because of their own experiences with Lucene. I would
really like to hear from anyone that has been working with metadata
particularly or anyone generally about these topics.
In my University job, I'm dealing with a fair bit of metadata in the
form of RDF about 19th century literature objects. I'm indexing basic
Dublin Core data such as title and author as individual fields, and
also dropping all indexed metadata into a single searchable field.
I've been using Kowari as the metadata store, but it also has Lucene
integration (that I've not tried myself yet).
I'm not sure what else to add as your query is a bit general. I think
you'll find if you post more specific questions you're more likely to
get detailed responses. General queries tend to be too general to
respond to, I find.
There really are no "best practices" with Lucene in terms of what to
index, what to store - these are all highly application dependent and
is often something I tune as the application itself evolves.
