Perhaps you should try some spelling variations:
information requirements » nutrition requirements, irrigation requirements, information environments
euclidean spaces » euclidean space
based pastes » based paste, based wastes, based pastures
based oaths » based path, based lathe, based coated
based math » based path, based mach, based mac

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

• Performing a fuzzy search may retrieve terms with similar spellings: information requirements ((((based oaths) or (based pastes))) or (based math)) euclidean spaces~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information requirements ((((based oaths) OR (based pastes))) OR (based math)) euclidean spaces.
• Adding a wildcard symbol may retrieve word variants: information requirements ((((based oaths) or (based pastes))) or (based math)) euclidean spaces*.
