Zend Lucene - 如何进行查询

Question

我的创建索引函数如下所示

function create()
{
    Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8_CaseInsensitive ());
    $index = Zend_Search_Lucene::create('data/index');      
    $doc = new Zend_Search_Lucene_Document();

    $doc->addField(Zend_Search_Lucene_Field::Text('title', 'a cheap car in town milage under 3000','utf-8'));
    $doc->addField(Zend_Search_Lucene_Field::Text('detail','a cheap car in town milage under 3000','utf-8'));
    $doc->addField(Zend_Search_Lucene_Field::Text('category', 'milage under 3000','utf-8'));

    $index->addDocument($doc);
}

当用户搜索“城镇里程低于3000的廉价汽车”时，我会将查询分为

$query1 = "a cheap car";
$query2 = "in town";
$query3 = " milage under 3000";

我要搜索的

$query1 in field "title", $query2 in field "detail", $query3 in field "category". 

3部分我也想搜索数字不区分大小写和文本不区分大小写。我该怎么做呢？我需要实际的代码，因为我对 Zend Lucene 文档完全感到困惑，我不知道要使用哪个代码或查询。

您的查询将是：

$query = Zend_Search_Lucene_Search_QueryParser::parse("title:($query1) detail:($query2) category:($query3)";
$hits = $index->find( $query);

索引不区分大小写，除非在创建时明确设置为区分大小写。
