Reply To: Product Variations Searchable but Show only Parent Products as Results

[Ernest Marcinko]

Hi!

I believe it is possible, and the only way is to use the index table engine, along with a custom code snippet.

First, make sure to configure the index table engine, only to index the product post type (and everything else you may want to search, except the product variations).
Then using this custom code, to append the variation information to the actual product:

add_filter( 'asp_post_content_before_tokenize_clear', 'asp_tokenize_sku_variation', 10, 2 );
function asp_tokenize_sku_variation($content, $post) {
  if ( $post->post_type == 'product' && ($variations = $_product->get_children()) ) {
	foreach ( $variations as $variation ) {
		$content .= ' ' . $variation->get_description();
		$content .= ' ' .  $variation->get_sku();
	}
  }

  return $content;
}

I have not been able to test this code for now. It should get all the variations for each product during indexing, and then append their SKU and descriptions to the main product. So searching variation data should yield the parent product as the result.
