Sorry, I'm not very much into Lucene's internal Classes, I'm just telling
your the viewpoint of a
user. You know my users aren't technicians, so answers like yours won't make
them happy.
It works for me too on linux. Thanks for the test!

If you use the Field.Text(String name, Reader value) version of the
Field.Text constructor, the field is tokenized and indexed but *not*
stored. This means you will be able to search and find that document,
but to know the original contents you will have to store a copy of it
elsewhere.

Hi all,
I am cross-posting my reply also to developer list because I think some of

order to better handle wild character expansion.

Yeah, it means an object you're trying to access is null. :))
You'll have to look at the JSP and see what object that is to
troubleshoot.

Hi;
I am using the HTMLParser that comes with the latest version of Lucene (in
the demo).
Here is the import line:
import org.apache.lucene.demo.html.HTMLParser;
If you have lucene-demos-1.4-final.jar in your class path the system will
find the Parser Class.
I am happy with the results.

Ah. That would explain it. Thank you Luc.

Luke,
I also integrated Lucene into a content management application with
incremental updates and ran into the same problem you did.
You need to make sure only one process (which means, no multiple copies
of the application writing to the index simultaneously) or thread ever
writes to the index.
Hi Luke;
Currently I am experimenting with checking if the index is lock using
IndexReader.locked before creating a writer. If this turns out to be the
case I was thinking of just unlocking the file.
Do you think this is a good strategy?
Thanks,
Luke

I am curious, though, how many people on this list are using Lucene
in the incremental update case. Most examples I've seen all assume
batch indexing.
I do both on for Simpy (simpy.com). To ensure no duplicates, I try to
delete (by some unique ID) before I add a new Document.

On Thu,
How do I know the number of documents to be optimized (If I have one
large index, number of documents that are in other segments) at any
time?
Thanks in advance,
Ravi.

Hello.
I have just encountered a way to get the QueryParser to throw an
ArrayIndexOutOfBoundsException. It can be recreated with the demo
org.apache.lucene.demo.SearchFiles program. The way to trigger it is to
parse a query of the form:

I think I have resovled my locking issues, at least in my development

Hi,
I am looking at the Similarity class overview, and wondering if I can
replace the SUM operator with a MAX operator, or any other operator
(across the terms in a query).
For example, if I search for car OR automobile, a BooleanScorer is
used to add the values from each subexpression together.

Hi;
Is there someway to determine if specific contents are in the index folder
other than running a query against it?
I see that my document is being indexed. But when I run a query against the
index I get no results returned.
The weird thing is if I restart TomCat and run the search again
If you add a Document to the index after you've opened an
IndexSearcher/Reader, your IndexSearcher/Reader will not see it. You
have to open a new IS/R to see the newly added Documents. This is
often covered on this list... I must have added this to Lucene FAQ at
jGuru, too.

You might wat to look at LUKE @ http://www.getopt.org/luke/

there
