The optimization process and recommendations:

1. Avoid Subqueries In From Clause (modified query below): The database cannot properly optimize subqueries in the FROM clause. Therefore, we recommend to extract the subqueries to temporary tables, index them and join to them in the outer query.
2. Avoid using too many joins (modified query below): Using too many joins can complicate the query's readability and the ability of the database optimizer to optimize the query.
3. Create Optimal Indexes (modified query below): The recommended indexes are an integral part of this optimization effort and should be created before testing the execution duration of the optimized query.
4. Explicitly ORDER BY After GROUP BY (modified query below): By default, the database sorts all 'GROUP BY col1, col2, ...' queries as if you specified 'ORDER BY col1, col2, ...' in the query as well. If a query includes a GROUP BY clause but you want to avoid the overhead of sorting the result, you can suppress sorting by specifying 'ORDER BY NULL'.

Optimal indexes for this query:

ALTER TABLE `es_temp1` ADD INDEX `es_temp1_idx_task_id` (`task_id`);
ALTER TABLE `es_temp10` ADD INDEX `es_temp10_idx_task_id` (`task_id`);
ALTER TABLE `es_temp11` ADD INDEX `es_temp11_idx_task_id` (`task_id`);
ALTER TABLE `es_temp12` ADD INDEX `es_temp12_idx_task_id` (`task_id`);
ALTER TABLE `es_temp13` ADD INDEX `es_temp13_idx_task_id` (`task_id`);
ALTER TABLE `es_temp14` ADD INDEX `es_temp14_idx_task_id` (`task_id`);
ALTER TABLE `es_temp15` ADD INDEX `es_temp15_idx_task_id` (`task_id`);
ALTER TABLE `es_temp16` ADD INDEX `es_temp16_idx_task_id` (`task_id`);
ALTER TABLE `es_temp17` ADD INDEX `es_temp17_idx_task_id` (`task_id`);
ALTER TABLE `es_temp18` ADD INDEX `es_temp18_idx_task_id` (`task_id`);
ALTER TABLE `es_temp19` ADD INDEX `es_temp19_idx_task_id` (`task_id`);
ALTER TABLE `es_temp2` ADD INDEX `es_temp2_idx_task_id` (`task_id`);
ALTER TABLE `es_temp20` ADD INDEX `es_temp20_idx_task_id` (`task_id`);
ALTER TABLE `es_temp3` ADD INDEX `es_temp3_idx_task_id` (`task_id`);
ALTER TABLE `es_temp4` ADD INDEX `es_temp4_idx_task_id` (`task_id`);
ALTER TABLE `es_temp5` ADD INDEX `es_temp5_idx_task_id` (`task_id`);
ALTER TABLE `es_temp6` ADD INDEX `es_temp6_idx_task_id` (`task_id`);
ALTER TABLE `es_temp7` ADD INDEX `es_temp7_idx_task_id` (`task_id`);
ALTER TABLE `es_temp8` ADD INDEX `es_temp8_idx_task_id` (`task_id`);
ALTER TABLE `es_temp9` ADD INDEX `es_temp9_idx_task_id` (`task_id`);
ALTER TABLE `staff_jobs` ADD INDEX `staff_jobs_idx_task_id` (`task_id`);
ALTER TABLE `tasks` ADD INDEX `tasks_idx_id` (`id`);
