mnoGoSearch是一个功能完整的Web搜索引擎,你可以用它来在HTTP,HTTPS,FTP,NTTP服务器,本地文件和数据库文本字段之上构建搜索引擎。它内置支持XML,HTML,eml和文本文件。外部转换器,可用于支持其它类型的文档。支持自动 70多种语言/字符集猜测。还支持群集,从而能够实现通过多台计算机分发数据,能够索引高达几百亿文件巨大集合。Mnogosearch是由dpsearch改良而来的,与php整合比较好用。
此扩展已被移至 PECL 资源库且不再与 PHP 捆绑。下载 http://www.mnogosearch.org/
PHP包含内置的MySQL访问库,可以用来访问MySQL。众所周知,mnoGoSearch与此内置库不兼容,只能与通用MySQL库一起使用。因此,如果将mnoGoSearch与MySQL一起使用,则在PHP配置期间,必须指明在mnoGoSearch配置期间使用的MySQL安装目录,例如:--with-mnogosearch --with-mysql=/usr。
Well since the function udm_get_res_param used with UDM_PARAM_NUM_ROWS does infact not get the number of rows on the current page, it can actualy find more rows than specified by UDM_PARAM_PAGE_SIZE, ??? well i had to rewrite the some stuff I also added highlightning since the parameter UDM_PARAM_HLBEG nor UDM_PARAM_HLEND doesnt seem to work, alot of things here are fairly undocumented, I also found out after reading the Search_Mnogosearch pear class that replacing "\2" and "\3" in the text with HLBEG and HLEND works. well here is the class rewritten (without fetch, just find): 
<?php
class MnogoSearch

  public  $matches = NULL;
  public  $total  = NULL;
  public  $hilites = array('title', 'text');

    if ($t == '')
      return '';
    $t = str_replace("\2", $this->hlbeg, $t);
    $t = str_replace("\3", $this->hlend, $t);
    return $t;
  }

        }
        foreach($this->hilites as $hilite) {
          $this->matches[$i][$hilite] = $this->hiLite($this->matches[$i][$hilite]);
        }
      }
      return $rows;
    } else {
      return FALSE;
    }

Im thinking, maybe swish-e is better ? :)for win32 users, mnogosearch since version 3.2.x
support COM interface
for Reflection API of COM use Visual Studio .NET
-> Tools ..
-> OLE/COM object viewer

</pre>I have found that if you compile php with "--with-ftp and --with-mnogosearch=/dir" you must compile and build mnogosearch with "--disable-ftp" first. There are some naming conflicts between php's ftp libs and mno's ftp libs. Hope this helps
