Karthik,
I don't think the boost in your example does much since you are using an
AND query, i.e. all hits will have to contain both vendor:nike and
contents:shoes. If you used an OR, then the boost would put nike
products above (non-nike) shoes, unless there was some other factor that
causes
I would be tempted to index the text fields but not save them. Since
Lucene returns everything as Otis pointed out, it's inefficent to keep
rarely used data in as content in the index. Put the text fields in a
database or a file tree somewhere and keep a pointer to it as a field in

I didn't want to let this drop this on the floor, but I haven't had the
time to craft a response to it either. So, just for the record I agree
that transactions would be nice. I think that it is important that the

Hi all.
I'm starting to use lucene and I wonder if it is possible to make a
query syntax to ask for one string which can be in two different fields
and filter duplicated results like with distinct in SQL syntax.
Something like:
distinct (+string OR OtherField:(+string))
Thanks a lot
I didn't pay full attention to this thread, but it sounds like somebody
may be interested in RuntimeShutdownHook (or some similar name) as a
place to try to release the locks.

Interesting idea, at the moment the file is created on disk, the
FSDirectory could add a shutdown hook that checked for the existence of
the file and if it's still there (implying that the Lock owner failed
without releasing the lock) it can forcably remove it.

Lucene only knows documents
If I understand what you are trying to do, you don't have a problem.
You can OR to your heart's content and Lucene will properly create the
union of the results. I.e., there will be no duplicates.
There is built-in support for this kind of thing. See
MultiFieldQueryParser, and for better

Thanks for the pointers, I have modified the Indexer.java to index the
files from the directory by removing the file extenstion check of

New situation is that when I run the FileSearch
