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');
    public   
$hlbeg   = '<span class="hilite">';
    public   
$hlend   = '</span>';

    protected
$agent   = NULL;
    protected
$res     = NULL;

    public function
__construct() {

       
$this->agent = udm_alloc_agent('mysql://user:pass@localhost/mnogosearch/');

       
$this->set(UDM_PARAM_SEARCH_MODE, UDM_MODE_ALL);
       
$this->set(UDM_PARAM_CHARSET, 'iso-8859-1');
       
$this->set(UDM_PARAM_BROWSER_CHARSET, 'iso-8859-1');
       
$this->set(UDM_PARAM_WORD_MATCH, UDM_MATCH_SUBSTR);

    }

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

    public function
set($k, $v) {
       
udm_set_agent_param($this->agent, $k, $v);
    }

    public function
find($q, $page=0, $rows=10) {

        if (
$page < 0 || $rows <= 0) {
           
$page = 0;
           
$rows = 10;
        }

       
$this->set(UDM_PARAM_PAGE_SIZE, $rows);
       
$this->set(UDM_PARAM_PAGE_NUM, $page);

       
$this->res = udm_find($this->agent, $q);
       
$this->total = udm_get_res_param($this->res, UDM_PARAM_FOUND);

       
$found = udm_get_res_param($this->res, UDM_PARAM_NUM_ROWS);

        if(
$found) {
           
$b = udm_get_res_param($this->res, UDM_PARAM_FIRST_DOC);
           
$e = udm_get_res_param($this->res, UDM_PARAM_LAST_DOC);
           
$rows = $e - $b + 1;

           
$fields = array('urlid', 'url', 'content', 'title', 'keywords', 'desc',
                           
'text', 'size', 'rating', 'modified', 'order', 'crc', 'category',
                           
'lang', 'charset', 'siteid', 'pop_rank', 'originid');

            for(
$i=0; $i<$rows; $i++){
                for(
$j=0; $j<count($fields); $j++) {
                   
$this->matches[$i][$fields[$j]] = udm_get_res_field($this->res, $i, $j+1);
                }
                foreach(
$this->hilites as $hilite) {
                   
$this->matches[$i][$hilite] = $this->hiLite($this->matches[$i][$hilite]);
                }

            }
            return
$rows;

        } else {
            return
FALSE;
        }
    }

    public function
__destruct() {
       
udm_free_agent($this->agent);
        if (isset(
$this->res)) {
           
udm_free_res($this->res);
        }
    }
}

?>

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

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
