Zend_Search_Lucene: UTF-8 madness


I hat some problems with Zend_Search_Lucene and non-english characters such as the german ÄÖÜ. My database returns UTF-8 formatted strings so I thought everything will work just fine.

After having serious encoding problems I searched the web and found, that the following lines of code solved the problems for most people:

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

In fact, this did not solved my Problem. Today I figured out a solution that works: (not the utf8_decode)

$doc->addField(Zend_Search_Lucene_Field::keyword('division', utf8_decode($contact->division)), 'utf-8');

Well, this is working perfectly fine, but frankly it looks quite odd. Why do I have to convert strings back and forth? Maybe I'm using Lucene wrong? Or is this a bug?


Solution

  • Querying and storing data are two different things . If your query is encoded in utf-8 then your data (document) should also be utf-8 encoded so to match the query .

    Lastly

    $doc->addField(Zend_Search_Lucene_Field::keyword('division', utf8_decode($contact->division)), 'utf-8');
    

    shd be

    $doc->addField(Zend_Search_Lucene_Field::keyword('division',$contact->division, 'utf-8'));
