In front-end search when a user searches with any keyword I need to call xyz API, it will return items based on this keyword.
Now I need to create products on the fly in Magento if those items not exist, otherwise, I need to update price.
Then I need to show the results in search result page based on the keyword as usual.
I followed link https://mage2.pro/t/topic/1121
But I'm not able to figure it out where I need to write my logic.
