Then the design would be buggy:

  The explicit phrase for "searchResults(myattribute=keywordList)" (in case
  "myattribute" is a keyword index) is:

	Find all objects that are indexed by "myattribute" for
	at least one keyword in "keywordList".

	Now, if "keywordList" is empty, no object can be
	indexed for at least one keyword in this list.
