# LXXXVIII. mnoGoSearch Functions

# Введение

These functions allow you to access the mnoGoSearch (former UdmSearch) free search engine. mnoGoSearch is a full-featured search engine software for intranet and internet servers, distributed under the GNU license. mnoGoSearch has a number of unique features, which makes it appropriate for a wide range of applications from search within your site to a specialized search system such as cooking recipes or newspaper search, FTP archive search, news articles search, etc. It offers full-text indexing and searching for HTML, PDF, and text documents. mnoGoSearch consists of two parts. The first is an indexing mechanism (indexer). The purpose of the indexer is to walk through HTTP, FTP, NEWS servers or local files, recursively grabbing all the documents and storing meta-data about that documents in a SQL database in a smart and effective manner. After every document is referenced by its corresponding URL, meta-data is collected by the indexer for later use in a search process. The search is performed via Web interface. C, CGI, PHP and Perl search front ends are included.

More information about mnoGoSearch can be found at http://www.mnogosearch.org/.

> Замечание: This extension has been moved to the PECL repository and is no longer bundled with PHP as of PHP 5.1.0.

> Замечание: Для Windows-платформ это расширение недоступно.

# Требования

Download mnoGosearch from http://www.mnogosearch.org/ and install it on your system. You need at least version 3.1.10 of mnoGoSearch installed to use these functions.

# Установка

In order to have these functions available, you must compile PHP with mnoGosearch support by using the `--with-mnogosearch`option. If you use this option without specifying the path to mnoGosearch, PHP will look for mnoGosearch under `/usr/local/mnogosearch` path by default. If you installed mnoGosearch at a different location you should specify it: `--with-mnogosearch=DIR`.

> Замечание: PHP contains built-in MySQL access library, which can be used to access MySQL. It is known that mnoGoSearch is not compatible with this built-in library and can work only with generic MySQL libraries. Thus, if you use mnoGoSearch with MySQL, during PHP configuration you have to indicate the directory of your MySQL installation, that was used during mnoGoSearch configuration, i.e. for example: `--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');
public $hlbeg = '<span class="hilite">';
public $hlend = '</span>';

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 ? :)`

`I finally got PHP 4.2.1 to compile with mnoGoSearch 3.2.2 ; trick is to build the shared mnoGoSearch and not the static version (opposite from mnoGoSearch defaults), and not to use --disable-rpath in PHP.`

`There is always a collisions for FTP name between PHP releease 4.2.0-dev and mnogosearch 3.2.3. So, first compile mnogosearch with --disable-ftp.`

`The name collision between php's builtin FTP functions and mnoGo's have been fixed since version 3.1.14 of mnoGoSearch according to; http://www.mnogosearch.ru/history.html`

25-Apr-2001 03:53
`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`
