All,
We have seen the following stacktrace in production with Lucene 2.3.2:
java.lang.IllegalStateException: abort() can only be called when
IndexWriter was opened with autoCommit=false
at org.apache.lucene.index.IndexWriter.abort(IndexWriter.java:2009)
at org.apache.lucene.index.IndexWr
Dear Karsten, thank for your help.
It`s so difficult. ^^;
Thank you again.

I just hope indexing one extra field isn't gonna be performance issue later.
Ty for your replies.

I am having some strange behavior and want to rule out that the query that I
am constructing is the correct way to deal with this type of query. This
is what I am working with:
I am creating a query that contains 3 different fields
Field 1: value - String
Field 2: type- String
Field 3:
Has anyone gotten some initial performance observations about
instantiated index?
I replaced my RAMDirectory searcher with one and it was slower or about
the same. The note about it claims 100x possible performance
improvement. Maybe there is a data size beyond which its performance
excels.

Hello,
We are currently using lucene v2.1 and we are planning to upgrade to lucene
v2.4.
Can we change the merge factor for an existing index and then add more
documents to that index? Is there some kind of upgrade path like using
optimize to move an existing index to a different merge factor?

Thanks for the tip!
I used the StandardAnalyser(Set stopWords) constructor and passed in an
empty stop words set.
Now my queries in OR look like this:
+lastname:rhodes +state:or
I think that solved the problem.

Sorry, those methods do indeed require 2.4.0 -- I forgot it was only
with 2.4.0 that we made them public.
If for some reason you can't upgrade, then you can always put your own
incRef/decRef wrapper around the IndexReader.

I was able to upgrade to the 2.3.2 version of Lucene... We do not have the
2.4.0 version in house ...
I am trying to facilitate downloading that version. I did notice that the

2.3.1 and 2.3.2 versions... How did you get aroun
OR is both a stopword and a reserved word In this
case you *probably* are getting hit by it being a stopword.
Changing your analyzer to not use stopwords is probably
the way to go, but beware that you should probably use the
same analyzer at index AND query time.
If you're using StandardAnalyz

Hi all,
I'm hoping this is an easy question. I have a Lucene index that contains
names and states, and I'm having an issue when the state is Oregon,
specifically OR. Below is an example of the query I pass in and the
query string that QueryParser builds below it.
This works for every state except
No, you have to build that in yourself It can be a bit
tricky defining how you indicate that lines are in a file, but
this has been discussed extensively so searching the mail
archive should get you some pointers.

query.toString() is your friend, as is Luke . Two things are
often the problem here.

Are you opening/closing your searcher and writer for each document?
If so, it sounds like you're not closing all of them appropriately and
that would be the cause of your memory increase. But you shouldn't
have to do that anyway. Why not just use the same IndexReader to
search and delete all your d
Hi,
I'd like to use Eclipse Birt in order to make reports based on Lucene index
content as if I use a database. The idea is to use SQL statement to read this
index with a JDBC wrapper like the one existing for LDAP
(http://www.openldap.org/jdbcldap/). Perhaps somebody already have done a

then you'll need to index another field that records that intention, or
just "know" which fields are intended to be multiple.

Hi Blured,
sorry I don't know anything about eclipse birt.
I recommend to start a new thread "eclipse birt with lucene" where you
describe your problem again in detail.
be aware that lucene don't know numerical values. lucene only knows strings.
best regards

Hi,
Thanks for this response. The fact is I'd like to make some select request to
read documents already indexed in a Lucene index in order to base a Eclipse
Birt dataSource and dataset on this index.

I would like to search a collection of "keyword"s with lucene.
A Document has one or many keywords. The keywords appear only once in a

for example:
Document_1 : ( "aa" "bb" "cc" )
Document_2 : ( "bb" "cc" )
Document_3 : ( "cc" "dd" )

Hi Blured,
if you are asking about integration of lucene and a DBMS, possible compass

if you think about using hibernate: I think there already exist a lucene

(Lucene`s index format changed very often.)
I can not find this information in wiki.
Where can I get that?
Does the same document or picture for index fomat?
