Perhaps you should try some spelling variations:
source dimensions » resource dimensions, course dimensions, resource dimension
circuits source » circuits course, circuits pour, circuits some
gauge spaces » large space, safe spaces, use spaces
whose spaces » phase spaces, whose race, loose space
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 source dimensions ((gauge spaces) or (((whose spaces) or (shape spaces))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication circuits source dimensions ((gauge spaces) OR (((whose spaces) OR (shape spaces)))).
• Adding a wildcard symbol may retrieve word variants: communication circuits source dimensions ((gauge spaces) or (((whose spaces) or (shape spaces))))*.
