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
PHP;">
class SoClass {
private $_xindex;
private $_xsearch;
private $_project;
public function __construct($project){
//载入引导文件
require_once 'lib/XS.php';
//初始化
$xs = new XS($project);
$this->_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); //<a href="/tag/zhichi/" target="_blank" class="keywords">支持</a>同义词<a href="/tag/sousuo/" target="_blank" class="keywords">搜索</a>，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<a href="/tag/sousuo/" target="_blank" class="keywords">搜索</a>，将<a href="/tag/sousuojieguo/" target="_blank" class="keywords">搜索结果</a>文档保存在 $docs 数组中
$count = $xs->search->count(); //<a href="/tag/huoqu/" target="_blank" class="keywords">获取</a><a href="/tag/sousuojieguo/" target="_blank" class="keywords">搜索结果</a>的匹配总数估算值
if($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);
// <a href="/tag/tianjia/" target="_blank" class="keywords">添加</a>或更新到索引<a href="/tag/shujuku/" target="_blank" class="keywords">数据库</a>中
if(!$update){
$this->_xindex->add($doc);
}else{
$this->_xindex->update($doc);
}}
public function delete($idArray){
//<a href="/tag/shanchu/" target="_blank" class="keywords">删除</a>索引(主键<a href="/tag/shanchu/" target="_blank" class="keywords">删除</a>array('1','2','3'))
$this->_xindex->del($idArray); }
public function addSynonym($word1,$word2){
$this->_xindex->addSynonym($word1,$word2);}
public function clearIndex(){
$this->_xindex->clean();}
}
?>
