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

An efficient quantum multi-proxy signature scheme was proposed recently, in which the original signatory Alice distributed her authority to several proxy signatories, and then each proxy signatory can sign the message for her alone. In this work, we give a cryptanalysis on this scheme and then point out an unnoticed problem that the proxy signatory must send the signed message to the verifier when he signs it, which is in conflict with the requirement of digital signatures. Furthermore, this problem will give a good chance for an unreliable proxy signatory to deny his signature on the message. Finally, an improved version is presented, which is more economical and practical with current technology compared with the original scheme.
