ios photos search error

When I search for any topic from the photos application on my iphone 12 pro device, sometimes I

get an error that there is no picture. then when I exit the application and

re-enter and search again with the relevant subject, it finds 10 photos. When I

exit and search again, it increases to 40. I have to wait until all the photos

are found. as if the device is doing re-indexing. I am using icloud+ service

and photos are synced to my cloud account. There was no such problem on my

previous 6s device. Even though I reset my iphone 12 pro, the problem did not

go away. apple turkey customer service couldn't find a solution to my problem

either.
