    Hi, Can you help us with hiding the products without price or zero price. Without activating the code this pre_get_posts is working, but all results are showing if plugin is activated.

    // Exclude out of stock products
    function hide_products_no_price( $query ) {
    if ( ! is_admin() && $query->is_main_query() ) :
    $query->set( ‘meta_query’, array(
    array(
    ‘key’ => ‘_price’,
    ‘value’ => ‘0’,
    ‘compare’ => ‘>’,
    ‘type’ => ‘NUMERIC’
    )
    ) );
    endif;
    }
    add_action( ‘pre_get_posts’, ‘hide_products_no_price’ );

    You could activate the WooCommerce inventory “Hide out of stock items from the catalog” option, and mark those items with no-stock. WPSOLR will de-index them.

    Actually, some products are in stock status with empty price, will this work ?

    Can’t you mark those products as out of stock?

    No, we have many products which makes tough to mark them individually… some code to exclude it would be better. Above code is working but without wpsolr activated.

    The following code in your functions.php should filter out your products without a price from indexing.
    Delete the content of your index to remove current indexed products with no price, then reindex.

    <?php
    
    use wpsolr\core\classes\WPSOLR_Events;
    
    /**
     * Modify the SQL query that retrieves all post types to be indexed, to remove products with some condition on _price
     */
    add_filter( WPSOLR_Events::WPSOLR_FILTER_SQL_QUERY_STATEMENT,
    	function ( $sql_statements, $parameters ) {
    		global $wpdb;
    
    		$model_type = $parameters['model_type'];
    
    		if ( 'product' === $model_type->get_type() ) {
    			/*
    			 * Use a WHERE sub query to filter out posts with _price not > 0
    			 * This is an exemple: fine tune your query as you like
    			 */
    			$sql_statements['WHERE'] .= " AND A.ID in (SELECT post_id from {$wpdb->prefix}postmeta WHERE meta_key = '_price' AND CAST(meta_value as SIGNED) > 0)  ";
    
    			/*
    			 * We could also use a JOIN
    			 * $sql_statements['JOIN'] .= '...' ;
    			 */
    		}
    
    		return $sql_statements;
    	}
    	, 10, 2 );
