Can「箱の中を手で探った」be shortened to 「箱を探った」?


By using default meanings, couldn't the title be shortened to:

> 箱を探った。

  1. Isn't `の中` so obvious, it is assumed to be the location you searched? If I were to search **under** the box, then I _would_ write `の下`?
  2. Isn't `手で` so obvious, it is assumed to be with what you searched? If I were to search with my **foot** , then I _would_ write `足で`?
  3. In _formal written_ Japanese, shouldn't you try to shorten your sentences as much as possible?
  4. Is the following correct usage of `暗黙了解':

> この例では、`の中`も`手で`も暗黙了解です。

I am only talking about _formal writing_. Unnecessary words are naturally used
in every language in conversation.




  1. 箱を探った usually means to search a box in a blind spot by touching the surface of it.
  2. Even without 手で, it's usually interpreted so.
  3. Not particularly.
  4. 暗黙の了解 is correct.




I would say either "箱の中を探った” or "箱を中を手で探った”.

箱を探った。is grammatically not wrong, but it just sounds not natural to me.
