Catalog fulltext search performance

[p24-max]

Preconditions and environment

• Magento version: 2.4.3-p3
• MariaDB 10.3.34

Steps to reproduce

• Enable mysql slow query log
• Create or import a large number of products (~50.000) into your catalog
• Open magento admin, navigate to catalog > Products
• Type a phrase into the full text search field and press enter
• Check slow query log, this query is logged:

  SELECT DISTINCT `e`.`entity_id`
  FROM `catalog_product_entity` AS `e`
  WHERE (`e`.`entity_id` IN (SELECT `catalog_product_entity`.`entity_id`
                         FROM `catalog_product_entity`
                         WHERE (`sku` LIKE '%my search phrase%')
                         UNION ALL
                         SELECT `t1`.`entity_id`
                         FROM `catalog_product_entity_varchar` AS `t1`
                                  LEFT JOIN `catalog_product_entity_varchar` AS `t2`
                                            ON t1.entity_id = t2.entity_id AND t1.attribute_id = t2.attribute_id
                         WHERE (t1.attribute_id IN (151, 187, 84, 73))
                           AND (t1.store_id = 0)
                           AND (IFNULL(t2.value, t1.value) LIKE '%my search phrase%')
                         UNION ALL
                         SELECT `t1`.`entity_id`
                         FROM `catalog_product_entity_text` AS `t1`
                                  LEFT JOIN `catalog_product_entity_text` AS `t2`
                                            ON t1.entity_id = t2.entity_id AND t1.attribute_id = t2.attribute_id
                         WHERE (t1.attribute_id IN (75, 85))
                           AND (t1.store_id = 0)
                           AND (IFNULL(t2.value, t1.value) LIKE '%my search phrase%')))

  At my machine this query takes 663ms to execute

Expected result

Backend product catalog fulltext search is faster when working with more products

Actual result

Fulltext search in catalog > products executes for ~3 seconds which is annoying when working with it whole day

Additional information

• Affects this file: vendor/magento/module-catalog-search/Model/ResourceModel/Search/Collection.php (_getSearchEntityIdsSql)
• Could be improved by using MATCH ... AGAINST ... https://dev.mysql.com/doc/refman/5.6/en/fulltext-search.html with a FULLTEXT index:

  create fulltext index catalog_product_entity_varchar_value_index
           on catalog_product_entity_varchar (value);
  create fulltext index catalog_product_entity_text_value_index
           on catalog_product_entity_text (value);
  create fulltext index catalog_product_entity_sku_index
  on catalog_product_entity (sku);

Example of improved query (lacks match of joined t2.value, this should be extracted into single query or UNION without join for performance reasons. Multiple MATCH AGAINST in single query slows down a lot):

SELECT DISTINCT `e`.`entity_id`
FROM `catalog_product_entity` AS `e`
WHERE (`e`.`entity_id` IN (SELECT `catalog_product_entity`.`entity_id`
                           FROM `catalog_product_entity`
                           WHERE (`sku` LIKE '%my search string%')
                           UNION ALL
                           SELECT `t1`.`entity_id`
                           FROM `catalog_product_entity_varchar` AS `t1`
                                    LEFT JOIN `catalog_product_entity_varchar` AS `t2`
                                              ON t1.entity_id = t2.entity_id AND t1.attribute_id = t2.attribute_id
                           WHERE (t1.attribute_id IN (151, 187, 84, 73))
                             AND (t1.store_id = 0)
                             AND MATCH (t1.value) AGAINST ('my search string')
                           UNION ALL
                           SELECT `t1`.`entity_id`
                           FROM `catalog_product_entity_text` AS `t1`
                                    LEFT JOIN `catalog_product_entity_text` AS `t2`
                                              ON t1.entity_id = t2.entity_id AND t1.attribute_id = t2.attribute_id
                           WHERE (t1.attribute_id IN (75, 85))
                             AND (t1.store_id = 0)
                             AND MATCH (t1.value) AGAINST ('my search string')));

Execution time: 90ms (vs. 663ms current implementation)

Hi @p24-max , Thank you for reporting and collaboration. Verified the behavior on Magento 2.4-develop instance with 30k products and mysql slow query log enabled. The Fulltext search in catalog > products executes for 2 to 3 seconds. We are considering this as feature request to improve the performance as this is existing behavior of Magento. Thank you.
