akcms 后台查询增加查询范围

admincp.php 文件里面

搜索：$sql_condition .= " AND title LIKE '%{$get_key}%'";

改成：$sql_condition .= " AND (title LIKE '%{$get_key}%' or string1 LIKE '%{$get_key}%' or source LIKE '%{$get_key}%' or aimurl LIKE '%{$get_key}%' or string2 LIKE '%{$get_key}%' or keywords LIKE '%{$get_key}%')";
