php实现搜索类封装示例_

1、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 */ 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-in

2、dex; $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

3、 条 $docs = $xs-search-search(); /执行搜索，将搜索结果文档保存在 $docs 数组中 $count = $xs-search-count(); /猎取搜索结果的匹配总数估算值 if($count) $data = array(); foreach ($docs as $key=$doc) $data$keypid = $doc-pid; $data$keynid = $doc-nid; $data$keycategory = $doc-category; $data$keyurl = $doc-url; $data$keyname = $xs-search-hi

4、ghlight(htmlspecialchars($doc-name); $data$keymessage = $xs-search-highlight(htmlspecialchars($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 $th

5、is-_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) $this-_xindex-addSynonym($word1,$word2); p
