Коментарии
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
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
- > C:\Program Files\mnoGoSearch\searchcom.dll

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 ? :)
