Yes, it is true that empty nested queries are not supported - your empty
parentheses. The exception is simply indicating that a right parenthesis is
not permissible immediately after a left parenthesis.
What effect were you trying to achieve? Or was that just a typo on your
part?
An empty top-level query typically defaults to matching all documents, or
"*:*", so if you want that effect, use:
docKey:*:*
Two other possibilities:
docKey:* -- all documents with a value in the field
*:* -docKey:* -- all documents with no value in the field
