Forse hai sbagliato a scrivere i termini di ricerca:
communications communication » communication communication, communicating communication, communication communicating
communication based » communication between
based extension » based extraction
index theorem » index theory
index tree » index free, index time, indexing tree

Potresti ottenere più risultati modificando la stringa di ricerca.

• Se esegui una ricerca fuzzy potresti trovare termini con grafia simile: communications communication based extension ((((index tree) or (index from))) or (index theorem))~.
• Se stai cercando di usare operatori booleani, devi inserirli IN MAIUSCOLO: communications communication based extension ((((index tree) OR (index from))) OR (index theorem)).
• Utilizzare caratteri jolly permette di reperire forme varianti dei termini: communications communication based extension ((((index tree) or (index from))) or (index theorem))*.
