vBulletin Tag Search page Meta problem

I have a forum using vbseo on it.I'm editing search_tag template to edit meta tags of the page because they are all duplicate by default.

What i wish is including title and category of first thread on results.

This is codes that makes thread title's appear

<td class="thead" width="75%">$vbphrase[thread] / $vbphrase[thread_starter]</td>
	<td class="thead" width="150" align="center" nowrap="nowrap">$vbphrase[last_post]</td>
	<td class="thead" align="center" nowrap="nowrap">$vbphrase[replies]</td>
	<td class="thead" align="center" nowrap="nowrap">$vbphrase[views]</td>
	<td class="thead" width="25%">$vbphrase[forum]</td>

Code (markup):

I tried $vbphrase[thread] and $vbphrase[forum] in meta's but they just returned Thread and Forum in every page.Not the titles of real threads.How can i make this happen?

That's how metas looked like edited

Thank you from now on.
