I need "Price Low to High" and "Price High to Low" sorting.
For this I have followed some guides which are referring to override
These solutions are only applicable for older version of Magento 2 (Which doesn't use elasticsearch)
For 2.4+ versions where elastic search is mandatory, this guide wont work.
I have also tried this solution: https://devhooks.in/blog/how-to-add-custom-sorting-in-category-of-magento2
After applying above solution, I have checked query log, and query is like this:
SELECT `e`.*, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price`, IFNULL(review_summary.reviews_count, 0) AS `reviews_count`, IFNULL(review_summary.rating_summary, 0) AS `rating_summary`, `stock_status_index`.`stock_status` AS `is_salable` FROM `catalog_product_entity` AS `e` INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.customer_group_id = 0 AND price_index.website_id = '1' LEFT JOIN `review_entity_summary` AS `review_summary` ON e.entity_id = review_summary.entity_pk_value AND review_summary.store_id = 1 AND review_summary.entity_type = (SELECT `review_entity`.`entity_id` FROM `review_entity` WHERE (entity_code = 'product')) INNER JOIN `cataloginventory_stock_status` AS `stock_status_index` ON e.entity_id = stock_status_index.product_id WHERE (e.entity_id IN (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)) AND (stock_status_index.stock_status = 1) ORDER BY FIELD(e.entity_id,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32), `minimal_price` asc
Which is clearly showing that Elastic search is applying sorting before toolbar and before collection.
I just need to sort by
desc order, for low to high and high to low
