也许你应该尝试一些拼写变化:
communication operators » communication operator, communication operations, telecommunications operators
operators methods » operator methods, operations methods, operator method
methods extending » networks extending, methods finding, methods enhancing
whose spaces » phase spaces, shape spaces, whose race
gauge spaces » large space, safe spaces, use spaces
tuple spaces » tuple space, type spaces, triple space

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication operators methods extending ((((whose spaces) or (gauge spaces))) or (tuple spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication operators methods extending ((((whose spaces) OR (gauge spaces))) OR (tuple spaces)).
• Adding a wildcard symbol may retrieve word variants: communication operators methods extending ((((whose spaces) or (gauge spaces))) or (tuple spaces))*.
