Perhaps you should try some spelling variations:
information requirements » nutrition requirements, irrigation requirements, information environments
requirements water » requirements based, requirements case, requirements a
functions ecole » functions role, functions second, functions euler
functions egfr » functions esf, functions error, functions euler
functions e.l » functions esf, functions euler
gives » given, give

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 water ((((functions e.l) OR (functions ecole))) or (functions egfr)) gives~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information requirements water ((((functions e.l) OR (functions ecole))) OR (functions egfr)) gives.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information requirements water ((((functions e.l) OR (functions ecole))) or (functions egfr)) gives".
• Adding a wildcard symbol may retrieve word variants: information requirements water ((((functions e.l) OR (functions ecole))) or (functions egfr)) gives*.
