php实现搜索类封装示例
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
/**
*SoClass.php
*索引与搜索类*/
classSoClass{
private$_xindex;
private$_xsearch;
private$_project;
publicfunction__construct($project){
//载入引导文件
require_once'lib/XS.php';
//初始化
$xs=newXS($project);
$this->_project=$project;
$this->_xindex=$xs->index;
$this->_xsearch=$xs->search;
$this->_xsearch->setCharset('UTF-8');
}
publicfunctionquery($keyWord,$row=20,$jnum=0){
$xs=newXS($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){
$data=array();
foreach($docsas$key=>$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));
}
returnarray('data'=>$data,'count'=>$count);
}
returnarray();
}
publicfunctionhotWord($num,$type='lastnum'){
return$this->_xsearch->getHotQuery($num,$type);
}
publicfunctionexpanded($keyWord){
return$this->_xsearch->getExpandedQuery($keyWord);
}
publicfunctionlastCount(){
return$this->_xsearch->getLastCount();
}
publicfunctionindex($data,$update=0){
//创建文档对象
$doc=newXSDocument;
$doc->setFields($data);
//添加或更新到索引数据库中
if(!$update){
$this->_xindex->add($doc);
}else{
$this->_xindex->update($doc);
}
}
publicfunctiondelete($idArray){
//删除索引(主键删除array('1','2','3'))
$this->_xindex->del($idArray);
}
publicfunctionaddSynonym($word1,$word2){
$this->_xindex->addSynonym($word1,$word2);
}
publicfunctionclearIndex(){
$this->_xindex->clean();
}
}
?>
