php实现搜索类封装示例_PHP

本文为大家分享了php实现搜索类封装示例，供大家参考，具体内容如下

_project = $project;    $this->_xindex = $xs->index;     $this->_xsearch = $xs->search;    $this->_xsearch->setCharset('UTF-8');  }   public function query($keyWord,$row=20,$jnum=0){     $xs = new XS($this->_project);    $xs->search->setFuzzy();    $xs->search->setAutoSynonyms();    $xs->search->setQuery($keyWord); //支持同义词搜索，默认打开    $xs->search->setLimit($row, $jnum); //设置返回结果最多为 5 条，并跳过前 10 条    $docs = $xs->search->search(); //执行搜索，将搜索结果文档保存在 $docs 数组中        $count = $xs->search->count(); //获取搜索结果的匹配总数估算值    if($count){      $data = array();      foreach ($docs as $key=>$doc){        $data[$key]['pid'] = $doc->pid;        $data[$key]['nid'] = $doc->nid;        $data[$key]['category'] = $doc->category;        $data[$key]['url'] = $doc->url;        $data[$key]['name'] = $xs->search->highlight(htmlspecialchars($doc->name));        $data[$key]['message'] = $xs->search->highlight(htmlspecialchars($doc->message));      }       return array('data'=>$data,'count'=>$count);    }    return array();  }   public function hotWord($num,$type='lastnum'){     return $this->_xsearch->getHotQuery($num,$type);  }   public function expanded($keyWord){     return $this->_xsearch->getExpandedQuery($keyWord);  }   public function lastCount(){     return $this->_xsearch->getLastCount();  }   public function index($data,$update=0){     // 创建文档对象    $doc = new XSDocument;    $doc->setFields($data);     // 添加或更新到索引数据库中    if(!$update){      $this->_xindex->add($doc);    }else{      $this->_xindex->update($doc);    }  }   public function delete($idArray){     //删除索引(主键删除array('1','2','3'))    $this->_xindex->del($idArray);   }   public function addSynonym($word1,$word2){    <i style="color:transparent">本文来源gaodai$ma#com搞$$代**码)网8</i><strong>搞代gaodaima码</strong> $this->_xindex->addSynonym($word1,$word2);  }   public function clearIndex(){     $this->_xindex->clean();  } } ?>
