Excluding a product_cat from results

[craigwilcox]

Describe your question

We group some products into a category that we want to exclude from search. For instance, class tickets, which aren't really products. Is there a way we could exclude that category from search results? Let's call the category "classes-events" as an example.

Thanks!

Hi @craigwilcox,

Certainly, you can achieve this by adding an additional filter to the Elasticsearch query using the ep_post_filters hook https://10up.github.io/ElasticPress/ep_post_filters.html. Your code will look something like this:

/**
 * Exclude category from search.
 *
 * @param array    $filters Filters to be applied to the query
 * @param array    $args WP Query args
 * @param WP_Query $query WP Query object
 */
add_filter(
    'ep_post_filters',
    function( $filters, $args, $query ) {
        if ( is_admin() ) {
            return $filters;
        }

        if ( ! $query->is_main_query() || ! $query->is_search() ) {
            return $filters;
        }

        $filters[] = [
            'bool' => [
                'must_not' => [
                    [
                        'terms' => [
                            'terms.product_cat.term_id' => [ 22 ], // Change 22 to the category ID you want to exclude.
                        ],
                    ],
                ],
            ],
        ];
        return $filters;
    },
    10,
    3
);

Since this isn't a bug and there is no further input is required therefore, I'm closing this issue.
