I am looking for a quick solution to expand queries so they will look for
synonms as well.
The same way WordNet is doing - it will looks for other words that mean the
same as written in the query.
So Synonyms and WordNet are better categories to describe what I need.
Any idea?

Hi
I've implemented the solution using the PageHitCounter from the link and I
have noticed that in certain instances I get a 0 score for queries like
"document OR aspectj".
has anyone else experienced this?

If I execute the following boolean query, document 0 is returned.

This might help you understand Lucene scoring better...
http://lucene.apache.org/java/2_4_1/scoring.html
The number of occurrences is not the sole determinant of a
document's score and boosting won't change that.
But I have to ask why counting words is important to you. What problem
are you try
First off, I would start by using Lucene's explain functionality to
see why one result appears before the other. The explain method will
tell you all the factors that go into scoring each of your results, as
it goes beyond just term frequency.

The Lucene FAQ has a Q, "How do I retrieve all the values of a
particular field that exists within an index, across all documents?"
and gives some code. However, it looks like that code returns only
unique values. How does one get all values including duplicates?

Hi...
This may/may not have anything to do with Lucene/Nutch, but I figured I'd
ask/post anyway.
I'm working on a project, dealing with courses/classes on college sites. I'm
trying to figure out how to create an automated process where I can create a
process to link a given faculty member to a gi

Well, it seems that your problem, as stated, is not soluble. You've
stated that the instructors have the same name but given us no clue
as to what other information you have access to. So there's nothing
to distinguish them.
So what other information do you have about the particular instructors?

I'm using Lucene 2.4.1 and I'm still getting an AlreadyClosedException when
trying to reopen an IndexReader. Here's the code I'm using, in case I'm doing
something wrong, there isn't an error if I don't close the old reader:
String indexPath = "C:\\Lucene\\test";
IndexReader reader = IndexReader
Hi
Please ignore the problem I raised. User error !
Sorry

Hmm... the code looks OK.
Though: can multiple threads call that method at the same time?
And: could in-flight searches be using the reader, when you close it?
If instead of opening with String indexPath, you pass in an
FSDirectory that you opened, do you still hit the

What you are trying to do is called record linkage. There is a fair
amount of info in the Lucene archives on this, see http://www.lucidimagination.com/search/?q=record+linkage
As Erick says, you will need more info than just the name to do
this. I doubt you will be able to get completely
Changing it to use the FSDirectory instead of the indexPath string seems to
work. thanks alot!

wasn't the problem since I was the only one testing it. here's the full
exception that was thrown:

Actually, the code I had previously was:
TermEnum e = reader.terms( new Term( fieldName, "" ) );
Collection values = new LinkedList();
while ( fieldName.equals( e.term().field() ) ) {
String text = e.term().text();
if ( text.length() > 0 )

Hi all,
I'm happy to announce a new release of Luke, the Lucene Index Toolbox.
As usually, you can obtain it from here:
http://www.getopt.org/luke
This release upgrades Luke to the Lucene 2.4.1 jars.
* New features and improvements:
o Added term counts p
That exception looks like it's from 2.4.0, not 2.4.1.
Can you double check your CLASSPATH?
