帝国CMS搜索支持多关键字词空格搜索结果

帝国CMS搜索优化(支持多关键字词空格搜索结果)

本方法带来的其他影响因素暂未测试（目前已知热门搜索关键字词调用的时候，关键字也是带有空格的。暂未发现其他）
简单优化了下官方的默认搜索系统，让搜索支持多个关键字词之间可以使用空格区分（两个关键词之间多少空格都无所谓，多个关键词也无所谓，都支持）

后台搜索记录截图：

修改方法，打开/e/search/index.php
1、找到：

//处理关键字
function SearchDoKeyboardVar($keyboard){
$keyboard=RepPostVar2(trim($keyboard));
$keyboard=str_replace(' ','',$keyboard);
return $keyboard;
}

修改为：

//处理关键字
function SearchDoKeyboardVar($keyboard){
$keyboard=RepPostVar2(trim($keyboard));
//$keyboard=str_replace(' ','',$keyboard);
/*xuan 搜索关键字优化*/
$keyboard=preg_replace('/[\s]+/s', ' ', $keyboard);
/*xuan 搜索关键字优化*/
return $keyboard;
}

2、找到：

//(有两处，修改第二处)
$where=$f." LIKE '%".$keyboard."%'";
7.0版为：
$where=$f." LIKE '%".str_replace(" ","%",$keyboard)."%'";

修改为：

/*xuan 搜索关键字优化*/
preg_match_all("/[^\s]+/s",$keyboard,$keyarr);
foreach ($keyarr[0] as $val){
$tj.=$f." like '%".$val."%' or ";
}
$where=substr($tj,0,-4);
/*xuan 搜索关键字优化*/

这样即可。
懒人直接复制以下代码替换/e/search/index.php中所有代码即可
