Adding Attributes in pedictive results

So i almost have it but im subpar on backend word. Anyways here is the code that needs to be edited.

Its located in the plugin dir classes/class-wc-predictive-search-filter.php

$item_html = '<div class="ajax_search_content"><div class="result_row"><a href="'.$link_detail.'"><span class="rs_avatar">'.$avatar.'</span><div class="rs_content_popup"><span class="rs_name">'.stripslashes( $product->post_title).'</span>'.$price_html.'<span class="rs_description">'.$product_description.'</span></div></a></div></div>';
						$rs_items['product'] .= $item_html.'[|]'.$link_detail.'[|]'.stripslashes( $product->post_title)."\n";

Now this is the code i want to add right after the title link

<div class="get-rarity"><?php echo htmlspecialchars_decode( $product->get_attribute( 'rarity' ) ); ?>&nbsp;</div>

So it would be something like this

$item_html = '<div class="ajax_search_content"><div class="result_row"><a href="'.$link_detail.'"><span class="rs_avatar">'.$avatar.'</span><div class="rs_content_popup"><span class="rs_name">'.stripslashes( $product->post_title).'</span><div class="get-rarity"><?php echo htmlspecialchars_decode( $product->get_attribute( 'rarity' ) ); ?>&nbsp;</div>'.$price_html.'<span class="rs_description">'.$product_description.'</span></div></a></div></div>';
						$rs_items['product'] .= $item_html.'[|]'.$link_detail.'[|]'.stripslashes( $product->post_title)."\n";

Anyways can someone with more experience than me give me the correct syntax for that to work?
