Question

On my IndexController i have

    {

    $index = Zend_Search_Lucene::create(APPLICATION_PATH . '/indexes');     

    foreach ($this->pages as $p) {
        $doc = new Zend_Search_Lucene_Document();

        $doc->addField(Zend_Search_Lucene_Field::unIndexed('page_id', $p['page_id']));

        $doc->addField(Zend_Search_Lucene_Field::text('page_name', $p['page_name']));

        $doc->addField(Zend_Search_Lucene_Field::text('page_headline', $p['page_headline']));

        $doc->addField(Zend_Search_Lucene_Field::text('page_content', $p['page_content']));


        $index->addDocument($doc);
    }
    $index->optimize();
    $this->view->indexSize = $index->numDocs();
    }

Answer 1

Try adding this to your bootstrap:

Zend_Search_Lucene_Search_QueryParser::setDefaultEncoding('utf-8');
Zend_Search_Lucene_Analysis_Analyzer::setDefault(
    new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8_CaseInsensitive ()
);

Answer 2

Except in the bootsrap code to add the third parameter encoding for text-based indexes

$doc->addField(Zend_Search_Lucene_Field::text('page_name', $p['page_name'], 'UTF-8'));
