Search still go through moved out folder

My initial structure:

Root Folder (0):
* Folder A
** Folder A1
*** Mess of data A1
** Folder A2
*** Mess of data A2

I use the search within Folder A, by calling search api (https://developer.box.com/reference/get-search/). It return data from A1 with data from A2.

I have moved the Folder A2 to the root folder:

Root Folder (0):
* Folder A
** Folder A1
*** Mess of data A1
* Folder A2
** Mess of data A2

When i started to do a search again after an hour of waiting within the Folder A, it still returns me the Folder A2 files.
