Ok, here's the code for vB.org queries...
Code:
<form action="https://vborg.vbsupport.ru/search.php" method="post">
<input type="hidden" name="s" value="">
<tr class="secondalt">
<td><a href="http://www.vbulletin.org/" target="_blank">vBulletin.org Search</a></td>
<td><input type="text" size="30" class="bginput" name="query"> <span id="submitrow"><input type="submit" class="bginput" name="Submit" value="vB.org" accesskey="s"></span></td>
</tr>
</form>
This
will work.

Also, hellsatan, I'll continue with that idea of search individual forums on vB.org. Thanks!
