Hi, and thanks for reading.

We created an action to customize the product appearance to display the short description on mouse over the product thumbnail. If the short description is empty then it only shows “view product”. The action works well on all site except on search results.

function mywp_product_hover() {

	global $post;
		
	if( ! has_excerpt() ) {
		$minides = '?View product!';		
	} else {
		$minides = $post->post_excerpt;
	}
	
	echo '<div class="overlay">' . $minides . '</div>';
	
}

add_action( 'woocommerce_before_shop_loop_item_title','mywp_product_hover', 15, 0 );

Here is a working example: https://laiamartinmakeup.com/pa_marcas/madara/page/4/

However, on search results, this action is ignored, and instead it shows an auto excerpt:

https://laiamartinmakeup.com/tienda/?s=protecting%20hand%20cream

Note the first product is the same on both links.

Any help would be appreciated, been looking to excerpt and trim filters with no luck. Looks like WC search is ignoring the action.

Many thanks in advanced,

Cheers
