Problem searching low rank words

Hi!, I am developing an application using Zend_Lucene_Search Framework.

it consists in some XML files that I index with Lucene.

Part of the code I use for index is this:

PHP Code:


			
//Field path to the XML file

$this->addField(Zend_Search_Lucene_Field::Text('path', $fileName/*,'utf-8'*/));



//Name of the XML file

$this->addField(Zend_Search_Lucene_Field::Text('nombre',$nombre_libro/*,'utf-8'*/));



//Category of the XML file

$this->addField(Zend_Search_Lucene_Field::Text('categoria',$categoria/*,'utf-8'*/));



... 

There are some code to extract the text of the XML file (using SimpleXML)

...



//Field Unstored to store the words of the xml file.

$this->addField(Zend_Search_Lucene_Field::UnStored('contents',$palabras,'utf-8'));

The structure is simple, I store the words of the XML file and the path to the

file, then when I make a search I now which file open.

After the indexation I use Lucene Index Toolbox 0.7.1 (www.getopt.org/luke/) to inspect the index. Is a Java

app that permits me see my indexes, and searchs on it.

The problem I have is that some words (with low rank) are not returned by my search code

in PHP using Zend_Lucene_Search framework.

I don't know if it helps but my index has 29684 words

Part of the code I use is this (is a simple code that try to find a single word):

PHP Code:


			
setlocale(LC_CTYPE, 'es_ES.utf-8');



$index = new Zend_Search_Lucene($pathToTheIndex);



$hits = $index->find(strtolower($buscar));

For example in my app devolped in PHP 5 with that code to search I try to find the

word "lucas" and get no results, but in the Lucene Index Toolbox I make the same

search and I get 7 hits.

I don't know if is a encoding problem (I think not) or I'am doing a bad search code.

greetings from Argentina, Gustavo.

Sorry for my English!!

I was using the 0.8.0 version of the Zend Framework.
I download the version 1.0.2 and the problem solve.
Thanks
