Hi all,
Before posting this question I have read a couple of old threads on this list
on ways to update an existing index. the conclusion was to recreate a new
index. unfortunalty this may not be possible in my case (please correct me if I
am wrong).
let me first describe what I am having
you can initiliaze your IndexSearcher in a Servlet Listner, and even warm it up
with few queries. that way when the user sends the first query it won't take a
long time to load the index in RAM.

Hi all,
my index size has grown too much and I keep getting outOfMemoryError after
running few searches. I am using all the RAM that the JVM is allowing me 2.6GB.
I am left with two solutions now, the easy and expensive solution is to upgrade
the hardware to a 64-bit System and use more RAM.
have a look at spring module 0.3. it has a lucene module which contains many
interesting classes LuceneIndexTemplate, LuceneSearchTemplate, and all kind of
factotires following spring concepts.
here is the url to the documentation: http://www.springframework.org/node/270

Hi all,
I need to be able to get specific documents out of the returned documents
without the need to retrieve all the other documents.
just to describe my case, the user is allowed to specify in the queryString the
page number and number of results to return. for example if a query returns
you have two choices that I can think of:
1- before adding a document, check if it does't exist in the index. you can do
this by querying on a unique field if you have it .
2- you can index all your documents, and once the indexing is done you can
dedupe. (Lucene has built in methods that can
I have tried to use the isCurrent() method IndexReader to figure out if an
index is merging. but since I have to do this evrytime I need to add a
document, the performance got s slow.
here is what I am doing, I create 4 indexs and I am running with 4 threads. I
do a round robbin on the
high
so that merges will never happen, and set maxBufferedDocs to the size
of the segments you want.

if you get an OutOfMemoryException, I beleive the only thing you can do
is just increase the JVM heap to a larger size.

this depends on the analyzer you are using, use luke and check that numbers are
actually in the index. if not then use an analyzer that does index numbers.

what you can do is open the index and loop through all the documents in
decending order.
the code below will explain more.
Directory dir = FSDirectory.getDirectory( args[ 0 ], false );
IndexReader reader = IndexReader.open( dir );
int numDocs = reader.numDocs();
HashSet items = new HashSet(
Hi guys,
I am writing an indexing applications that writes to 4 different indexes. the
way it work is the following: I write to one index every 1 documents and
then close that index and call optimize() as well, at the same time I write to
the second index and close it after 1 docs and
Hi guys,
If a field is indexed as UnStored how can I get it value?
I tried document.get(UnStored_field) it returns null.
thanks

hi guys,
is it possible to filter the hits returned from a certain query?. for example
if I have a search like this:
Query searchQuery = queryParser.parse( query );

is there a way to use the results and find out how many of the
I have 5 indexes, each one is 6GB...I need 512MB of Heap size in order to open

can I store an instance of MultiSearcher(OR just Searcher in

developing an aplication to search using the analyzer that was used while
indexing.
my concern now is if there is an error with the way the indexing was do I have
to reindex the documents?
