Error with com_search when you search string

"string++string" or "string+++string" (replace + by blank character). Example:

Code:

"a a"

http://www.joomla.org/index.php?option= ... rd=a++a....

SOLUTION:

http://physicist.phpnet.us/2007/05/28/j ... ch-glitch/

et’s come on a site joomla.org and click on the Search menu item. Now we enter text “test test” for search (with three spaces between words!). As a result of the search the huge document with a lot of “” is received.

To get rid of this glitch, it is necessary in a file /components/com_search/search.php after a line

$searchword = strval( mosGetParam( $_REQUEST, 'searchword', '' ) );

(or, in older versions

$searchword = $database->getEscaped( trim( $searchword ) );

) add

$searchword = preg_replace( '/\s{2,}/s', ' ', $searchword );

It will allow to remove a series of spaces from the search query.

Search Website Joomla! (1.0.x and 1.5) by "a a" or "a a a" or "a a a a" ...

Because this code (about line 177 in com_search/search.php)

Code:

<?php
foreach ($searchwords as $hlword) {
   $text = preg_replace( '/' . preg_quote( $hlword, '/' ) . '/i',
       '<span class="highlight">\0</span>', $text ); 
}

Firstly, this problem has no way degrading the performance of Joomla! as PHP/MySQL doesn't work harder.

Second, I think I have a short solution. Modification of components/com_search/search.php:

At about line 74, after

Code:

$searchword = strval( mosGetParam( $_REQUEST, 'searchword', '' ) );

add

Code:

$searchword = preg_replace('/[\s\.\\\+\*\?\[\^\]\$\(\)\{\}\=\!\<\>\|]+/', ' ', $searchword);

At about line 185, replace

Code:

foreach ($searchwords as $hlword) {
      $text = preg_replace( '/' . preg_quote( $hlword, '/' ) . '/i', '<span class="highlight">\0</span>', $text );
}

with

Code:

$text = preg_replace('!(' . implode($searchwords, '|') . ')!i', '<span class="highlight">\1</span>', $text);

The first one remove dirty space (which returns indesirable results), the second avoid looped "
It works for me (http://thongtincongnghe.com).

The com_search of Joomla is far from perfection.
