更新一个索引

//更新多一个索引 $index = new Zend_Search_Lucene(INDEX_DATA); Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8_CaseInsensitive()); $doc = new Zend_Search_Lucene_Document(); $doc ->addField(Zend_Search_Lucene_Field::unStored('key',md5($rid),'utf-8')); $doc ->addField(Zend_Search_Lucene_Field::text('logTitle',$data['logTitle'],'utf-8')); $doc ->addField(Zend_Search_Lucene_Field::text('logContent',$data['logContent'],'utf-8')); $index->addDocument($doc); $index ->optimize(); $index->commit();

删除索引

//删除索引 $index = new Zend_Search_Lucene(INDEX_DATA); Zend_Search_Lucene_Search_QueryParser::setDefaultEncoding('utf-8');//设置查询器编码，搜索中文必须！ $hits = $index ->find(md5($id)); foreach ($hits as $hit){ $index->delete($hit->id); } $index -> commit();

修改索引

//更新修改索引 $index = new Zend_Search_Lucene(INDEX_DATA); Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8_CaseInsensitive()); Zend_Search_Lucene_Search_QueryParser::setDefaultEncoding('utf-8');//设置查询器编码，搜索中文必须！ $hits = $index ->find(md5($id)); foreach ($hits as $hit){ $index->delete($hit->id); } $doc = new Zend_Search_Lucene_Document(); $doc ->addField(Zend_Search_Lucene_Field::unStored('key',md5($id),'utf-8')); $doc ->addField(Zend_Search_Lucene_Field::text('logTitle',$data['logTitle'],'utf-8')); $doc->addField(Zend_Search_Lucene_Field::text('logContent',$data['logContent'],'utf-8')); $index->addDocument($doc); $index->optimize(); $index -> commit();
