Talvez debería tentar con algunhas variantes ortográficas:
irrigation requirements » irrigation equipment, nutrition requirements
requirements data » requirements a, requirements case, requirements based
data dimensions » data dimension, data dimensional, dark dimensions
bioarrays » bioardays, bioarray, bioarways
rays » days, ray, ways

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 data dimensions (((bioarrays OR bioarray) from) OR (rays from))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements data dimensions (((bioarrays or bioarray) from) or (rays from))*.
