Back with more detail. This is what I have in my navbar template. Try it in your search results template
Code:
<form action="search.php" method="post">
<input type="hidden" name="do" value="process" />
<input type="hidden" name="showposts" value="0" />
<input type="hidden" name="quicksearch" value="1" />
<input type="text" class="bginput" name="query" size="31" value="$search[query]"/> <input type="submit" value="Search EA" />
</form><br><span align="right" class="smallfont"><a href="/forums/search.php?">Advanced Search</a> </span>
