Hello,
I created small Lucene's application which stores lot of my users
infomation, on of it is zipcode in numeric format eg. 50501, 63601 -
zip codes are stored in Text fields so they are fully searchable what
I want now to do is getting all unique zipcodes which was stored so
far. Something like
Hi,
Actually lucene does not provide you a straight forward Query to get UNIQUE
results.
But as far as I know, u can use HitsCollector & BitSet combination to
count/get unique results.

This example code gets the unique terms for a field
and a total num docs for each...
String fieldName="myfield";
valueCounts=new ArrayList();
TermEnum termEnum;
termEnum = indexReader.terms(new Term(fieldName,""));
Term term = termEnum.term();
while (term!=null)
{
if (!fieldName.equals(ter
The IndexReader.terms() method gets a list of all the terms in an index.
You need to somehow limit this to the terms for your ZipCode field which I
don't know how to do. Luke has the ability to do this though so it is
certainly possible.

Paul I.
There is one little note. If index has deletions then counters could
have wrong values...

Hello,
I am using lucene for storing details of my students. I have used
SetUseCompoundFile(True) and optimised the indexes. Now I am not able to
convert them back to their original form
Thanks in advance

Hi, I've been trying to show the query results in a reverse-chronological
order,
and found out that the best way to do so is to pre-sort them if possible,
so that, when searching, the relevant documents are shown in the
reverse-chronological order(the most recent document at the top) even
without r
I was reading up on conversion of characters to UTF-8 and I now understand
why it is writing out UTF-8 (to be able to support most of the worlds
languages with minimal space?). But after reading up on the algorithms for
conversion as given below, does the writeChars method not support the

Lucene doesn't currently output totally valid UTF-8
Patches to make it do so are here:

Should this be tackled pre or post 2.0?

Is this modified UTF-8 such as is found in DataInput interface?

I saw an implementation of folksonomy with Lucene...does anyone know about that
or seen it?
According to the Lucene In Action book you can convert from one compound to
multi-file and vice versa by setting the setCompoundFile method to true or
false. But in running this myself I found that while I can convert from
multi-file to compound, it doesn't convert back. Here is the code that I

It's no secret that Otis' wonderful Simpy is powered by Lucene.
I'm in the process of building a folksonomy-based application that

I would be interested in seeing that...and then converting it to DotLucene :)
Keep me updated!

I talked about this a bit in a presentation at Haifa last year:

Hi
Is anyone aware of subclasses of the Similarity class in Lucene? Two subclasses
are: DefaultSimilarity and SimilarityDelegator . Are any other implemented
subclasses of Similarity, developed by anyone else available on the web? For
example, Language Model based similarity, or Okapi-BM simi
I presume the patch that gives us a way of overriding the default
timeout for write locks has made it into the source DB, but I really
need a jar file to point people at which contains it. Any chance of
a 1.9.2 release?

Hello,
Thanks for your responce.
can you please guide me on how to break this single index into multiple pieces.
when I try to do so it corrupts the index.
I had created a index with max merge docs set to 10,000 with set compound
indexes set to true. now I called optimize with max merge docs set
Does changing the merge factor
and setting the options to SetUseCompoundfile(false)
split a single index into multiple pieces.
Even i have been doing something similar and would like to know how it is
done
