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

The article delves into the intriguing phenomenon of multipartite mixed maximally entangled (MME) states, which exhibit the same entanglement as pure states. It begins by recapping the bipartite case, where mixed states can have the same entanglement as maximally entangled pure states. The article then extends this concept to N-partite systems, defining conditions for MME states and providing a detailed derivation of these conditions. Practical examples and tests are presented to illustrate the application of these findings. The work concludes by highlighting the potential applications of multipartite MME states in quantum teleportation and remote state preparation, suggesting exciting avenues for future research.
