search 2 or more keywords or words separated by a space

Hi ,

I would like to know if it possible to modify my code

so I can search 2 or more keywords or words separated by a space or another word or a DOT or an underscore or a (-) or a (+) or a (%) or (anything else lol).

Now only accept a keyword for searching.  If input 2 keywords.  It won't get result.

Search field code:

<form method="POST" action="searchResults.php">
<input name="title,intro_keyword" type="text" value="" size="16">
<input type="submit" name="submit" value="Search" class="btn">
</form>

searchResults.php - header

<?php
/* STEP 1: LOAD RECORDS - Copy this PHP code block near the TOP of your page */

// load viewer library
$libraryPath = 'cmsAdmin/lib/viewer_functions.php';
$dirsToCheck = array('/home/quanmax/public_html/','','../','../../','../../../');
foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

list($productsRecords, $productsMetaData) = getRecords(array(
'tableName' => 'products',
'perPage' => '10',
'loadUploads' => true,
'allowSearch' => true,
));
?>

searchResult.php - Body

<table width="700" border="0" align="center" cellpadding="0" cellspacing="5">
<tr>
<td>Here are results of your search.</td>
</tr>
<tr>
<td> <?php foreach ($productsRecords as $record): ?>
</p>
<table border="0" cellspacing="0" cellpadding="0" width="700">
<span
id="news_list_lab">
<tbody>
<tr>
<td width="185" valign="top" class="content_s_000"><?php foreach ($record['images'] as $index => $upload): ?>
<img src="<?php echo $upload['thumbUrlPath2'] ?>" alt="<?php echo htmlencode($record['title']) ?>" width="<?php echo $upload['thumbWidth2'] ?>" height="<?php echo $upload['thumbHeight2'] ?>" hspace="20" /><br/>
<?php endforeach ?></td>
<td align="left" valign="top" class="content"><b> <a href="<?php echo 'products-detail.php?num='.$record['category'];?>"> <?php echo htmlencode($record['title']) ?> </a> </b> <?php echo $record['intro']; ?></td>
</tr>
<tr>
<td colspan="2" align="right" class="line_h_dot_black"><a href="<?php echo 'products-detail.php?num='.$record['category'];?>"><img
class="banner_line_no" hspace="0" alt="See More!" vspace="5"
src="images/share/button_more.gif" width="41"
height="11" /></a></td>
</tr>
</tbody>
</span>
</table>
<p>
<?php endforeach ?>
</td>
</tr>
</table>

Hope there is a simple way to get it.

Thanks!
