Loerie, if you have been reading the tech forum, the answer to your criticism of the search will be found there.
Very simply, search aircraft overflew the location of the crash on the day of the crash (June 1) and saw nothing. Why they saw nothing is a matter that needs to be examined.
But the logical thinking would be if you don't find evidence of the crash on the day of the crash when you overfly the crash location, then the plane didn't crash there. The result of them not seeing evidence on June 1 led them to searching elsewhere in the days, months, and years that followed.
