I am facing issue while queering the Task from MWS. I used TaskSearchInbox Query which fetches only 999 tasks.
So i also TaskSerchQuery which also fetches only 999 tasks.
There is any limitation in using Task API.
I can see the below info message in MWS logs.
task:INFO - All Tasks Task Search Query [max:1000]
Retrieving a very large number of tasks puts a great deal of load on the server and will kill overall performance. Do you have a use case where it is necessary to retrieve that many tasks?
You may want to look at the searchTasksPaged API method that allows you to page through a set of tasks, rather than retrieving them all at once.
