The details and the code in this FAQ allow alkaline to run on the same port as your web content, demonstrates boolean and or not operator implementation, and provides php the result next and results count to be parsed within the overall html document as separate variables. It also disallows the * search string, if so required.
Create two php files both with the same name (i.e index.php).
Place one file in your alkaline server directory and the other in your root web directory.
Ensure the directories also have the same name, i.e. http://www.foo.com:9999/bar/index.php should correspond with http://www.foo.com/bar/index.php.
Copy and paste the following code into your alkaline php document.
<!--SET MAP--
<table>
<tr>
<td width="5%"> </td>
<td><a href="$url">$title</a></td>
<td align="right" width="5%">$quality%</td>
</tr>
<tr>
<td><a href="$url">*</a></td>
<td colspan="2">
<br>$header ...
<br>$size bytes; modified: $modif
</td>
</tr>
<tr>
<td colspan="2">url: <a href="$url" >$url</a></td>
<td> </td>
</tr>
</table>

<!--SEARCH-NEXT-->
<!--SET NEXT--<B>next</B>-->
<!--SET C-BEFORE--<b><font color="red">-->
<!--SET C-AFTER--</b></font>-->
<!--SET N-BEFORE--<b class="block4">-->
<!--SET N-AFTER--</b>-->

<!--SEARCH-RESULTS-->

Copy the following code into your web server php document.
<?php

// doesn't allow this as this provides optimal retrieval time
$server = "localhost"; // server that Alkaline runs from
$port = "9999"; // port that Alkaline runs from
// the following two must be identical on your web server and Alkaline server
// ie www.foo.com/search/index.php must correspond to
// www.foo.com:9999/search/index.php

$docname = "index.php"; // name of this script.
// define Alkaline variables
$boolean = "on"; // allow AND OR NOT boolean terms
$allrecords = "off"; // ensures * cannot be used to return all records
// main section
$rawsearch = urldecode($search);

$rawsearch = urldecode(substr(stristr($QUERY_STRING, "search="), 7));
