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

Based on the quantum asymmetric encryption with trapdoor information, a quantum public-key signature scheme is proposed. In our scheme, the signer signs a message with his/her private key, while the verifier verifies the quantum signature with the corresponding quantum public key. The signer’s private key and public key are asymmetric, and the signing algorithm and verifying algorithm are asymmetric as well. The security of the private key depends on the unconditionally secure deterministic quantum communication protocol rather than the classical one-way function. All the algorithms in our scheme are public. Hence, our scheme obeys Kerckhoffs’s principle. Our scheme is secure against forgery, repudiation, and eavesdropping attacks. On the other hand, in our scheme, the verifier need not perform any quantum swap test. The signer’s key pair can be reused due to the secrecy property of the private key. Compared with similar schemes, ours is relatively more secure and efficient.
