This method did work, but I still think it is a very aggressive practice, since it cleans the inbox abruptly. There are not many options to choose from.
If at least it allowed you to choose the other boxes, such as sent, draft or archive, it would be better.
I must say that the method worked, but I lost a lot of important information. I chose a period of 7 days, but it even searched for things from previous years...
Right now I am distressed and I don't even know how to recover the information I lost...
