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

A controlled quantum dialogue with authentication protocol on a basis of GHZ-like state was proposed in this paper. To start with, three participants of the communication protocol generated a corresponding identity ID through quantum key distribution and it was kept secret. Controller Trent prepared the three-particle Greenberger–Home–Zeilinger-like (GHZ-like) state and shared with other two communication users Alice and Bob. Communication participants use the entangled particles in their respective hands which satisfy the nature of the classical XOR relationship for encryption, controlling and decryption of quantum messages and to verify the identities of communication users. Meanwhile, security of communication was assured by introducing decoy photons. According to analysis results, the proposed protocol can effectively not only prevent any form of eavesdropping behavior from external and internal eavesdroppers including the controller Trent, but also detect such activities. Finally, this protocol is proved to have high communication efficiency.
