xunsearch实战经验总结

一、定义好配置文件(非常关键)

  a):如果需要做精确搜索建议对字段设定index=self,tokenizer = full,不然xunsearch会对字段做分词处理;

  b):数字区间搜索需设定 type=numerice;

  c):如需对字段进行模糊匹配tokenizer 可不设定,默认做scws分词,如字段存储的值为“,6,7,8,”想搜索包含6或8的数据;

  d):配置文件必须包含一个type=id的主键字段

配置文件参考手册:http://www.xunsearch.com/doc/php/guide/ini.guide

二、搜索  addQueryString()

  a):字段搜索  

   $this->_xs_search->addQueryString('style_sn'.':"'.$condition['style_sn'].'"');

  b):IN搜索 

foreach ($list as $value){ 
      $query.="{$key}:{$value} OR ";
   }
$this->_xs_search->addQueryString(rtrim($query,"OR "));

  

  c):区间搜索

  $this->_xs_search->addRange('shoucun',$condition['shoucun_min'],null); //大于最小值
 $this->_xs_search->addRange('goods_price',$condition['price_min'],$condition['price_max']);

  

  d):like搜索

           不设定tokenizer默认支持模糊搜索

   $this->_xs_search->addQueryString('style_sn'.':"'.$condition['style_sn'].'"');

  e):排序

   排序字段建议采用数字类型(非必须) 

      

  $order=array("goods_click"=>1);
    if (count($order) > 1) {
      $this->_xs_search->setMultiSort($order);  //多个排序字段
    } else {
       $this->_xs_search->setSort($order);
    }

  

  d):分组 (setCollapse)

    $this->_xs_search->setCollapse($this->_collapse,1)->setLimit($page_size,$begin);

  f):返回总数不正确

//解决总条数(getLastCount()/count())统计不准确问题
//原理:重新查询一次并设定Limit,如果超过实际总数将返回正确的记录条数
$this->_xs_search->setCollapse($this->_collapse,1)->search();
$count = $this->_xs_search->setCollapse($this->_collapse,1)->getLastCount();   
$total_page = ceil($count/$page_size);
$begin = ($total_page-1)*$page_size;
$this->_xs_search->setCollapse($this->_collapse,1)->setLimit($page_size,$begin);
$this->_xs_search->setCollapse($this->_collapse,1)->search();
$count = $this->_xs_search->setCollapse($this->_collapse,1)->getLastCount();
$this->_indexer_count = $count;

  

注意:
如果出现10061错误或连接被拒绝,请在安装目录bin文件夹下执行此句命令:./xs-ctl.sh -b inet start
