也许你应该尝试一些拼写变化:
communication controllers » communication controller, communication controlling, communication control
controllers control » controllers central, control control, contactless control
control extensions » central extensions, central extension, control extending
tuple spaces » tuple space, triple space
type spaces » state spaces
safe spaces » state spaces, shape spaces, scale spaces

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication controllers control extensions ((((tuple spaces) OR (type spaces))) or (safe spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication controllers control extensions ((((tuple spaces) OR (type spaces))) OR (safe spaces)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication controllers control extensions ((((tuple spaces) OR (type spaces))) or (safe spaces))".
• Adding a wildcard symbol may retrieve word variants: communication controllers control extensions ((((tuple spaces) OR (type spaces))) or (safe spaces))*.
