Talvez debería tentar con algunhas variantes ortográficas:
irrigation requirements » irrigation equipment, nutrition requirements
requirements patterns » requirement patterns, requirements water, requirements chapter
functions error » functions entire
functions e.l » functions esf, functions ecole, functions euler

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

• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements patterns ((functions e) OR (((functions e.l) OR (functions error)))) lives~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements patterns ((functions e) or (((functions e.l) or (functions error)))) lives*.
