Does anyone know how to link to the product's main category from the search result page? It seems impossible to do but nothing is impossible, right? I tried:

<a href="home.php?cat={$current_category.parentid}">test1</a>
<a href="{$location[1][1]}">{$location[1][0]}</a>
<a href="home.php?cat={$subcat.categoryid}">test3</a>
<a href="home.php?cat={$category.categoryid}">test4</a>
<a href="home.php?cat={$c.categoryid}">test5</a>
<a href="home.php?cat={$products[product].categoryid}">testA</a>
<a href="home.php?cat={$product.categoryid}">testB</a>
<a href="home.php?cat={$products.categoryid}">testC</a>

Every product has a main category ID link, I can see it when I check an item in the backend of our store. I want customers to be able to access the main category from the search result page since we have no actual product pages (we use category pages where people can buy the products). Thanks in advance!
