You can feed the hits vector into Quaere (http://quaere.codehaus.org/) to
accomplish the SQL-like grouping you desire, very easily. But I'm not sure
it'll be that much quicker. Worth a shot.

I think u may need to use escape function to escape the words which does not

Checkout for "http://www.ibm.com/developerworks/web/library/j-lucene/";
Though this page does not list a comparison between SAX and Digester, it
convinced me enough to use Digester

Hi,
Checkout for the following lines in the documentation of IndexReader:
* "An IndexReader can be opened on a directory for which an IndexWriter
is opened already, but it cannot be used to delete documents from the
index then. "
* "Once a document is deleted it will not appear in TermDocs or

Hey!
Search for the topic "Aggregating Category Hits" in the list. You'll get
a few approaches that you may use to implement "groupby".

Dear Fellow Lucene Developers:
I am a java/jsp developer and have started learning lucene for the purpose
of creating a search engine for some books that I have in xml format. The
XML document is actually quite large, and would like to provide as accurate
results as possible to the user searchin
Correction: that issue to watch out for is in regards to the TopDocs
HitCollector. If you where to go with your own HitCollector rather than
TopDocs you might not necessarily have this problem (or at the least you
can code around it).

Hey Haroldo.
First thing you need to do is *stop* using Hits in your searches. Hits
is optimized for some pretty specific use cases and you will get along
much better by using a HitCollector.
Hits has three main functions:
It caches documents, normalizes scores, and stores ids associated wit

Please use the tool Luke to have a look inside your index to see if a
document with field "uid" and the uid you're expecting really exists. The
field should be UN_TOK
Hallo *;
I went through some examples of the Lucene in Action book to find that the
API has changed and then applied the corrections with the help of this
forum.
One runtime problem however remains. I cannot delete any documents.
I store documents like this:
IndexWriter iw = new IndexWriter(
I apologize for cross-posting but I believe both Solr and Lucene users
and developers should be concerned with this. I am not aware of a
better way to reach both communities.
In this email I'm looking for comments on:
* Do TokenFilters belong in the Solr code base at all?
* How to deal
Can you explain the problem you're trying to address from the user's
perspective?
From the description you've provided, you may want to look up
"Faceted Searching". Another option may be to use a HitCollector,
but it would help us if you could describe the problem at a higher
level.
Re
I have a problem of performance when I need group the result do search
I have the code below:
for (int i = 0; i < hits.length(); i++) {
doc = hits.doc(i);
obj1 = doc.get(Constants.STATE_DESC_FIELD_LABEL);
obj2 = doc.get(xxx);

It's a list of terms with optional flags. For example:

In a different file, the flag "x" would then be defined as "appe

If it is so, then as I understand it is actually possible to create some
analyzer which gets ispell dictionary as parameter

You don't have to, but it helps improving recall.

It depends on the dictionary. Some dictionary authors use the ispell
flagging system
I was wondering about methods for analyzing various languages and that
what I understand (please correct me if I wrong):

Hi,
I'm wondering if there is a kind of "formule" to estimate the size of a
lucene index. Searching the list, I did not find any pointers.
Does anybody has a hint?
What I figured out from the file format description and some empirical
tests is, that for every index-file:
Field-files:
field-dat
