Unlike for doc values fields, Lucene does not store this information
(which documents have a given indexed field) efficiently and so there
is no query for it.

If this is important to you, you could add another field for each
indexed field?  E.g. if the document has field foo, you would also
index has_field_foo e.g. as a StringField with the same text token
like "1".  Then at search time you can do a TermQuery on
