Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

Quantum digital signature offers an information theoretically secure way to guarantee the identity of the sender and the integrity of classical messages between one sender and many recipients. The existing unconditionally secure protocols only deal with the problem of sending single-bit messages. In this paper, we modify the model of quantum digital signature protocol and construct an unconditionally secure quantum digital signature protocol which can sign multi-bit messages at one time. Our protocol is against existing quantum attacks. Compared with the previous protocols, our protocol requires less quantum memory and becomes much more efficient. Our construction makes it possible to have a quantum signature in actual application.
