Perhaps you should try some spelling variations:
complete discussion » complete disjunction, comments discussion, complete description
circuits complete » circuits complexity, circuits computer, circuits coupled
tuple spaces » tuple space, type spaces, triple space
scale spaces » scale space, sample spaces
shape spaces » shape space, shared spaces, state 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 circuits complete discussion ((tuple spaces) or (((scale spaces) or (shape spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication circuits complete discussion ((tuple spaces) OR (((scale spaces) OR (shape spaces)))).
• Adding a wildcard symbol may retrieve word variants: communication circuits complete discussion ((tuple spaces) or (((scale spaces) or (shape spaces))))*.
