[Avatar: The Last Airbender] Couldn't Toph find the space sword trivially?

It fell from a blimp into a forest. Toph has the ability to find things through tremors in the ground. Wouldn't this make finding Sokka's magical space-sword a trivial exercise?

No.

She has to be in contact with the same ground in close vicinity to sense stuff, so she wouldn't have sensed where it landed.

On top of that Aang flooded the battlefield which would most likely have buried the sword or swept it out to sea, or at least swept it into a different location. And even if they wanted to look for it later, the battlefield looked like it was hundreds of square miles - that's a lot of area to search, a real needle in a haystack situation.

Like the other guy said, shit's gone.
